t.A.T.u. was a duo girl group consisting of Lena Katina and Yulia Volkova, originating from Moscow, Russia. Internationally speaking, they are the most renowned band to ever come out of Russia, routinely playing to audiences of 50,000 fans and selling more than 5 million copies of their debut album, ''200 KM/H in the Wrong Lane''. The two girls met when they were thirteen years old and were both members of a children's vocal and instrumental group called "Neposedy" ("Naughty Children"). At fourteen, Ivan Shapovalov cast Lena Katina in his new project and she recorded the single, "Yugoslavia," about NATO's bombing of Yugoslavia. Shortly after, Ivan decided to add another female singer and chose Yulia Volkova. The name t.A.T.u. is originated from the original Russian Cyrillic name for the band "Тату". In Russian language, ‘ta (та)’ means ‘that [female]’ and ‘tu (ту)’ also means ‘that [female]’ to be a shortened version of the Russian phrase 'Ta lyubit Tu (та любит ту)', meaning ‘This girl loves that girl’. Their first single, "Ya Soshla S Uma (I've Lost My Mind)," or the English version "All The Things She Said" dealt with a love affair between two girls. The song was set to a music video where Yulia and Lena were depicted in Catholic schoolgirl uniforms imprisoned in some form of cage while a crowd of people look on as they kiss in the rain and try to escape. At the end, there is an ironic twist where the girls escape and it is revealed the crowd were the ones truly imprisoned - by their own minds. Their music videos only became more controversial, with "Prostye Dvizheniya (Simple Motions)," depicting Yulia masturbating while Lena went about her daily routine. During this phase, they released the Russian ''200 Po Vstrechnoy'' and the English version ''200 KM/H In The Wrong Lane''.

Infamously, they refused to perform at the World Music Awards unless provided with real guns. Lena said, "We wanted real machine-guns, but they didn't give us, so we wouldn't perform, that simple." Brazenly, after promising not to kiss on ''TheTonightShow'', they engaged in a long, passionate wet one-- much to the alarm of anxious network censors, (and well before [[LesYay Britney and Madonna's little stunt]]). And yet, when expected to do the same on Jimmy Kimmel, they deliberately censored themselves. Yulia said, "Basically, because we like to do what we want, a lot of people are, like, 'you shouldn't do this, you shouldn't do that, you shouldn't behave in this way.' But you know what? Actually for us, we are the way that we are, and we don't really live in fear of anybody. So, if we behave in a certain way, then that's just actually the way we are."

In 2004, t.A.T.u. legally fired Ivan Shapovalov, their producer, from their project because they did not believe he took their music seriously. Yulia Volkova said, "He spends his time [[NoSuchThingAsBadPublicity thinking up scandals]] instead of planning our artistic work. I'm sure our fans would rather hear new songs and new albums than new scandals." Lena Katina added, "He made us out to BE lesbians when we were just singing FOR lesbians. We wanted people to understand them and not judge them. That they are as free as anyone else." They reformed after Yulia had her baby in 2004 and produced a Russian album, "Lyudi Invalidy (Invalid People)" and the English counterpart, "Dangerous and Moving." Their first single was released with a similar flair of controversy, as Yulia was portrayed splattering a potential rapist's brains against the wall.

The most recent album, "Vesyolye Ulybki (Happy Smiles)," and ''Waste Management'' in English is also the soundtrack for TheMovie, ''You and I''(previously known as "Finding t.A.T.u.") which is based on the novel "t.A.T.u. Come Back". The film features Mischa Barton and centres around two girls that meet on the internet due to their common love of t.A.T.u. Their relationship then becomes the catalyst for a series of adventures. The content of the movie has drug use, disturbing scenes and images, sexual content, and coarse language. t.A.T.u. has stated the movie will be very scandalous, and would not deal with the "love and roses" often found in films, but the real scandal and hardships that come along with relationships.

With their relationship deteriorating and both girls having mutual desires to start solo careers and distance themselves from their "t.A.T.u." images, Volkova and Katina parted ways and t.A.T.u. broke up in early 2011. Aside from a quick reunion in 2012, Katina and Volkova have generally been out of contact with each other.

Things started looking up in late 2013 and early 2014, with a few one off appearances and rumors of a new single or album. However, fans were devastated after Lena posted on her YouTube that she was breaking off the reunion due to Yulia's management essentially giving her a "my way or the highway" ultimatum and threats of shutting down her solo career within Russia. They did, however, reunite to perform 'Not Gonna Get Us' at the opening ceremonies of the 2014 Sochi UsefulNotes/OlympicGames during Team Russia's entrance.

As it turns out, they did manage to record one song together during this time, a Russian language only song called "Love in Every Moment", to be featured in a short film. By the time the song came out, their relationship had deteriorated to the point of their scenes for the music video being recorded seperately, and the song being billed as "Julia Volkova and Lena Katina".

As for their solo careers, both have continued the tATu sound in different ways. Lena's songs follow the soft rock and piano ballad style of some of their songs, while Julia's songs have an electropop edge like the third albums. The difference is highlighted by their first singles. "Never Forget You" is Lena's rock-infused sendoff to the band featuring a funeral in the video, and "All because of You" is an electronic song about wishing she didn't love a girl, with a video featuring a Lena lookalike getting jealous of her boyfriend and killing them with a bomb, much like the 30 Minutes video.

!!English Discography
* ''200 km/h in the Wrong Lane'' (2002)
* ''Dangerous and Moving'' (2005)
* ''Waste Management'' (2009)
!!t.A.T.u. contains examples of:
* AnimatedMusicVideo: [[http://www.youtube.com/watch?v=TVGS1XjFpe0 Gomenasai]].
* AssholeVictim: Yulia's [[AttemptedRape would be rapist]] in the music video of "All About Us".
* AuthorAppeal: t.A.T.u. was created by Shapovalov generally as an outfit for him to fulfill his sexual fantasies and desires, which was the main driving force of their early public image (the schoolgirl outfits, faux lesbianism, etc.). A large controversy erupted around the "All The Things She Said" video with many politicians and commentators viewing it as generally pedophiliac in nature (Lena and Yulia were 14-15 when it was filmed, and it depicts them kissing each other in schoolgirl outfits, with upskirt {{Panty Shot}}s thrown in for good measure). Shapovalov's response? He admitted that he was attracted to underage girls and that he thought up the idea for the group while surfing underage porn on the internet.
** How far did Shapovalov take it? Early publicity photos of the girls in school uniforms included pictures of them [[http://www.lazygirls.info/Tatu/Look_At_My_Panties_oIX23y8?display=fullsize spreading their legs with their panties in clear view]], and pictures of [[http://i33.tinypic.com/2dwf3pj.jpg Lena sitting on the toilet]]; he also forced them to strip each other out of their schoolgirl outfits while performing on stage. Shapovalov's firing came largely from the girls becoming tired of being his FetishFuel.
* BaitAndSwitchLesbians: Lena and Yulia. Shortly after coming out as heterosexuals, Yulia told the world that she was bi and Lena started to suggest that their sexual attraction wasn't ''entirely'' nonexistent. And at many concerts and interviews they still kiss each other.
* TheBaroness: Lena in the music video for "White Robe".
* {{Bifauxnen}}: Early Yulia.
* BiTheWay: Okay, so that whole thing about them being lesbians? That's not true, but really, Yulia is bisexual. This time she means it. No, really.
** There's also a great deal of speculation about Lena, due to her ambiguous statements saying that she "doesn't believe in orientation, only love."
* {{Blipvert}}: "''Prostye Dvizheniya''", "How Soon is Now?", "Ne Ver, Ne Boysia, Ne Prosi"'' and "Clowns/''Klouny''".
** The video for "How Soon Is Now?" had Yulia and Lena select the clips, and their ideas were put together by editors and other technical experts.
* BoomHeadshot: How Yulia kills her would be rapist in the controversial "All About Us" music video.
* BreakupSong: Arguably every song on ''Dangerous and Moving.''
** Meta example is "Never Forget," a song Lena wrote about Yulia after the duo disbanded in early 2011.
* CatholicSchoolgirlsRule: An IconicOutfit associated with the group.
* ComingOutStory: Arguably the entire first album (though moreso the English version than the Russian version).
* ConceptAlbum: ''200 km/h in the Wrong Lane'' is mainly about realizing and coming to terms with being gay, as well as the problems that can come with it (feeling different and being outcast). ''Dangerous and Moving'' consists mostly of {{Breakup Song}}s.
* CoverVersion: They once covered "[[Music/TheSmiths How Soon is Now]]", a version which was featured in ''Series/{{Charmed}}''.
* DamselOutOfDistress: Yulia in the music video for All About Us". [[BoomHeadshot And holy shit how!]]
* ADateWithRosiePalms: Julia in the video for "A Simple Motion".
* DeadpanSnarker: Both of them, especially during interviews. Two of the most cited examples: [[http://www.youtube.com/watch?v=r2i9g5nfqCE The Frank Skinner Show 2005]] and [[http://www.youtube.com/watch?v=uxb8KdLr1_M TV Total Germany 2003]].
-->'''Lena''': They're soooo sexy.
-->'''Frank Skinner''': Who?
-->'''Yulia''': When boy kiss each other and girl... No like?
-->'''Frank Skinner''': Not boys... I think, boys, I find them too hairy.
-->'''Lena''': No, there is such a thing, like, um, ''shaving'' thing.
-->(audience laughs)
-->'''Frank Skinner''': Yes... now I've got a Russian woman on the show telling me about shaving. Times have changed.
-->'''Stefan Raab''': You know how they call you? The Russian Lesbians.
-->'''Lena''': Oh... fuck.
-->'''Yulia''': You Germany Gay.
* DramaticIrony: Their (so far) last single titled "Love in Every Moment" was released at the time where the duo are in very bad terms, to the point that they shot its music video separately and that their only scene "together" is filled by a FakeShemp of Lena.
* DressHitsFloor: Lena's clothing in the video for "Beliy Plaschik" or "White Robe".
* EvenTheGirlsWantHer: Both Lena and Yulia have plenty of female fans.
* FaceHeelTurn: Yulia during both breakups:
** Slammed Lena's efforts in a 2009 interview while the group was still together (mainly criticising her for performing tATu songs in her solo shows, which she has since started doing HERSELF). Lena stated that she was very hurt by this.
** Her first solo song "Rage" was basically telling Lena to go away.
** In 2014, told Lena that the reunited tATu would be run her way, and if Lena didn't like it, she'd replace her and sabotage Lena's career in Russia. Lena naturally baulked at this and revealed the whole threat on her YouTube, at the same time torpedoing their reunion permanently.
** Utterly cemented by her statement that she'd condemn her son if he turned out gay. For comparison, Lena spends her summers playing gigs at gay pride festivals.
* FanDisservice: See AuthorAppeal above.
* FanservicePack: They were marketed for {{Fanservice}} by their original manager, but since he later admitted that he's doing this for his own FetishFuel, plus the way he "packaged" them, makes it more FanDisservice-y. Eventually however, the girls found their own way to show their sex appeal.
* FauxYay: Obviously Lena and Yulia.
* FlippingTheBird: Done a lot during the ХУЙ ВОЙНЕ (Rougly translated from Russian: "fuck war") era, mostly in photoshoots.
* GameBreakingInjury: Julia's VocalDissonance was actually caused by their original manager forcing her to constantly scream in their earlier songs.
* GayAesop: Perhaps the entire first album.
* {{Gayngst}}: Possibly the entire first album. "All the Things She Said" is the most glaring example. (its original Russian title even goes "I've Lost My Mind")
* GenreShift: From Eurodance to Pop Rock to Electronic Rock to Electronic Dance Pop.
* GirlOnGirlIsHot: Lena and Yulia. Also, their backup dancers.
* GirlsBehindBars: Yulia in ''Beliy Plaschik/White Robe''.
* GoryDiscretionShot: The censored version of the controversial "All About Us" music video only implies the BoomHeadshot. Also, a pregnant Yulia being executed wasn't shown in the music video for "White Robe".
* GratuitousJapanese: The song title "Gomenasai"
* GrayRainOfDepression: The set for the "All The Things She Said/''Ya Soshla S Uma''" video.
* HairContrastDuo: FieryRedhead and AloofDarkHairedGirl.
* IconicOutfit: Guess what?
* IncompatibleOrientation: "Malchik Gay", literally meaning "gay boy."
* {{Japandering}}: They reunited in 2013 for a Japanese [[https://www.youtube.com/watch?v=-nBflqmcdPc Snickers commercial]].
* KaleidoscopeEyes: Lena.
* LightFeminineDarkFeminine: Lena is usually the Light Feminine, while Yulia is usually the Dark. They both toy with this trope a lot though.
* LingerieScene: Lena in the beginning of the "White Robe" music video.
* LongRunnerLineUp: While there were a few pauses, Lena and Yulia performed together for 12 years until the 2011 split, with many a reunion afterwards.
* LostInTranslation: The English versions of their songs often have very different lyrics from the original, while keeping the same general meaning.
* MeaningfulRename: Subverted. Yulia now goes by the Anglicized version of her name, Julia, while Lena has not done the same (which would be Helen). Despite this, it's Lena who prioritises English markets, and Julia who prioritises Russian markets.
* NewSoundAlbum: ''Dangerous And Moving'' - some people consider it as a BaseBreaker album.
** Also, ''Happy Smiles/Waste Management''.
* OlderThanTheyLook: They're 29 in the last video, but Julia looks 25, and lena could still pass for a teenager.
* QuirkyCurls: Early Lena.
* PantyShot: Mostly in the music video for "All The Things She Said". In the video for "All About Us", Julia is seen in her underwear before the AttemptedRape, while "White Robe", Lena is explicitly shown changing in one scene. In concerts, Julia mostly wears leotards.
* PeekABangs: Majority of Yulia's hairstyles.
* RapeAsDrama: In the video for "All About Us", Yulia shoots a man who attempts to rape her and splatters his brains against the wall.
* RavenHairIvorySkin: Yulia early in the duo's run. She eventually tanned.
* RefugeInAudacity: Julia and Lena are respectively Muslim and Orthodox Christian. They also live in a very conservative country. You wouldn't be able to tell any of this by watching their videos.
** Julia's solo career is a particular offender. Frequently she makes out with women or makes songs about being in love with a woman. GirlOnGirlIsHot is probably the only thing keeping her out of jail.
* RedOniBlueOni: Yulia is the red to Lena's blue.
* RomanticTwoGirlFriendship: What Lena called their relationship after they were called on using homosexuality for publicity.
* RuleOfSymbolism: Their last music video has them in separate rooms and during "their" only scenes "together", it shows "them" standing back to back before "they" start arguing. The ending scene also features Yulia in a Lena wig hugging herself. The promotional materials also have them in separate portraits.
* SchoolgirlLesbians: Their early days were all about this image.
* SexySoakedShirt: In "All The Things She Said".
* SiameseTwinSongs: A rather obscure example: "Show Me Love" and "30 Minutes". The ''"Mama, Papa, forgive me"'' part at the end of "Show Me Love" is sometimes mistakenly referred to as the beginning of the song "30 Minutes".
* SopranoAndGravel: Lena and Yulia respectively, kind of. In terms of natural singing voice, Lena's is high and Yulia's is lower. In the early days of the band, Yulia would match Lena's range by basically screaming, giving their music this effect. eventually, this damaged Yulia's voice, and she now sings much lower.
* StalkerWithACrush: Their song "Fly on the Wall".
* TheMockbuster: Some could argue that the Russian girl duo ''TEMA'' is this. Their songs sound in some ways similar to t.A.T.u.'s and they once attempted to pass off their song ''Kto Esli Ne Ya'' as a t.A.T.u. song to gain publicity.
* TheMovie: A couple years ago, a movie called ''Finding t.A.T.u.'' (released in English with the title of one of their songs, ''You and I'') was released starring [[Series/TheOC Mischa Barton]] and [[Series/OneTreeHill Shantel]] [[Film/FinalDestination4 VanSanten]] about two girls so obsessed with t.A.T.u. that they involved themselves in a series of dangerous events.
* TitleOnlyChorus: ''Nichya''
* TheyKilledKennyAgain - Their videos:
** They run over their manager in "Not Gonna Get Us"
** Yulia performs a suicide bombing on Lena and her lover in "30 Minutes"
** "White Robe" features Yulia being executed, with Lena actually giving the order
** "Snowfalls" has them crashing into eachother on their bikes to evade police capture (This was their last video iin Russian or English, essentially marking the group as being dead)
** Lena's solo debut "Never Forget" is set at their mutual funeral. Possibly from the bike crash.
* ThoseTwoGirls: Literally what their name means in Russian.
* TitleTrack: ''Dangerous And Moving''.
* VocalEvolution: As noted in other entries, [[MetalScream the constant screaming]] during the early days took its toll on Yulia's voicebox, and her singing voice changed as a result.
* WanderlustSong: "Not Gonna Get Us" exploits running away, with no set destination, to share their love.
* WeUsedToBeFriends: Their relationship as of this edit is reportedly still sour.
* WhatBeautifulEyes: Perhaps Lena's main physical asset.
* WhiteShirtOfDeath: Subverted in the video of [[ExactlyWhatItSaysOnTheTin "White Robe"]]. Julia takes off the titular robe before she gets executed.
* WouldHurtAChild: The music video for "White Robe", which tackles abortion.
* YaoiFangirl: Those ladies suuuuuuuure like their [[YaoiGuys sexy gay guys]]
** [[SubvertedTrope Well]]... [[http://www.huffingtonpost.com/2014/09/19/tatu-singer-gay-son-yulia-volkova_n_5850098.html not so much for Yulia anymore]]...
