->''"I guess you guys aren't ready for that yet... But your kids are gonna love it."''
-->-- '''Marty [=McFly=]''', ''Film/BackToTheFuture''

Sooner or later, a time traveler will need to impress the historical types with an artifact or idea from his own era. Sometimes, this may be as simple as ThisIsMyBoomstick; but if said time traveler is a teenager with a penchant for music, these primitive screwheads are about to witness [[TitleDrop A Little Something We Call Rock And Roll]].

Reactions vary, but a historical culture will usually be shocked and terrified, unprepared as they are for a squealing, vaguely Van Halen-esque electric guitar solo. Gradually or suddenly, but often by the time the time traveler has solved their problems (and perhaps learned something himself) rock is accepted, and mundane medieval or prehistoric life will be just a little more "in your face" than our hero found it.

Future civilizations are not immune to this {{trope}}. Those which have forgotten their roots may be initially bemused by the crude back beat rhythm, but will learn to "get down" with it. In other cases, they might view the time-traveler's music as "classical" or see it as stuffy "old people" music.

In seriously reality-challenged situations, the time traveler may be able to construct or otherwise produce an electric guitar capable of all the feedback and distortion necessary for a properly face-melting, dad-enraging solo. In other cases, she may have simply brought a walkman or reproduce rock-like sounds on period instruments. The ultimate pinnacle of radness occurs when our hero has cobbled together a complete band of historical persons and taught them to build and play crude drum sets and keytars built from available materials. Bonus points if they have somehow discovered and harnessed electrical power to make this work.

It's a similar situation when a historical person is brought from the past to the present. This also increases the likelihood of their adopting present day music and slang. And CoolShades.

Compare GivingRadioToTheRomans, in which other types of modern technology are given to past civilizations.

Note: As with ThePowerOfRock, "Rock" in this {{trope}} can be replaced by any form of popular music from the movie's "present". For instance, in a movie is a comedy about the differences between Martin Lawrence and 10th century Britain, funk may be introduced.

[[folder:Comic Books]]
* JimmyOlsen is "The Red-Headed [[Music/TheBeatles Beatle]] of 1,000 B.C.!" (''Franchise/{{Superman}}'s Pal Jimmy Olsen'' #79, 1964) Hooray for the SilverAge indeed.
* Now for a non-time-traveling example. [[Creator/BongoComics Radioactive Man]] (yes, [[WesternAnimation/TheSimpsons Bart Simpson's]] [[{{Defictionalization}} favorite superhero]]) is a nuclear-powered heroic being who gained his super powers in 1952 and [[DiscoDan hasn't altered his technological or cultural sensibilities since]]. On his last adventure before [[EarnYourHappyEnding being reunited with his long-lost parents]], in 1996, RM ventures out into the city on a dark and stormy night to confront the neocommunist villain Dr. Crab, who plans to use a device called an airwave silencer to censor all the city's radio and TV networks for disseminating "capitalist propaganda." After winning a fight with another villain in an alley, RM is starting to round a street corner when he hears [[HellIsThatNoise an ominous "DOOM, DOOM, DOOM!"]] approaching the intersection. RM is frightened by the sound, and wonders if Dr. Crab "has some weird, fiendish new weapon." But just as he is preparing for a possible fight to the death, the sinister sound is revealed as nothing more than a ghetto blaster pumping out hip-hop beats as it is carried by a Music/VanillaIce-like teenager. (RM gives him a stern lecture about staying out past curfew.)
* {{Lampshaded}} in an early Magazine/{{MAD}} parody of ''ComicStrip/FlashGordon'' called "Flesh Garden", in which the evil alien emperor pits Flesh Garden against the great enemy of all - a man in boxing gloves.

[[folder:FanFic]]
* ''Fanfic/MyMetal'', a MyImmortal Music/HeavyMetal {{Parody}} by Creator/MonicaGilbeyBieber has Rainblood introduce Tom Riddle to heavy metal music by playing [[{{Music/Metallica}} Fade to Black]] for him on a guitar that can operate only on magic. The consequences of this action are then heavily deconstructed in the next chapters.

[[folder:Film - Animated]]
* Although TimeTravel wasn't involved, a variant appeared in the movie ''FernGully: The Last Rainforest'' when Zac uses his walkman to start a dance party with the fairies to Guy's cover of "Land of a Thousand Dances".
[[/folder]]

[[folder:{{Film}} - Live-Action]]
* ''BillAndTedsExcellentAdventure'' has multiple variations of this trope:
** Bill and Ted quote Kansas' "Dust in the Wind" to Socrates. Socrates does not speak English, instead interpreting it as "Like sand through the hourglass, so are the Series/DaysOfOurLives!"
** [[LudwigVanBeethoven Beethoven]] is thrilled to find a Casio keyboard in the San Dimas mall and immediately amalgamates a classical melody with 80s-style pop (Extreme's "Play With Me"). It sounds oddly baroque, despite Beethoven being from the 19th century. (The song itself is [[http://www.youtube.com/watch?v=6eGWuP6aLbI "Do You Want To Play"]] in a condensed form.)
** And, of course, the Princesses, who by ''Bill And Ted's Bogus Journey'' have not only joined the Wyld Stallyns, but well surpassed Bill and Ted in both musicianship (and modern English grammar). With Bill and Ted, that's not very difficult.
* In ''Film/BackToTheFuture'':
** Marty utilizes a walkman and Van Halen tape to scare the crap out of 1950s George [=McFly=], claiming he is [[Franchise/StarWars Darth Vader]] from the planet [[Franchise/StarTrek Vulcan]]. Later, Marty takes the stage at the sock hop and plays "Johnny B. Goode" to the teenagers' delight. A band member is so impressed he phones his cousin, [[InThePastEveryoneWillBeFamous Chuck Berry]], implying a StableTimeLoop. Marty then lapses into a wailing hair metal solo that terrifies everyone and inspires the page quote.
** Indeed, 'kid goes back in time and invents rock and roll' was one of the main premises the movie was built round.
** A deleted scene that makes it into the novelization goes further, incorporating a reference to [[Series/BattlestarGalacticaClassic the original Battlestar Galactica]] while Marty brandishes a hair-dryer as if it were a dangerous weapon, among others. The director thought it was a waste of time to show the entire scene (which is much longer than the scene that made the final cut) when George sums it up in a few seconds.
** For the record, the year to which Marty travels back is 1955, which is at least three years late to be the ground zero of rock 'n' roll.
* This trope is de rigueur in modern adaptations of ''Literature/AConnecticutYankeeInKingArthursCourt''.
** Despite predating rock 'n' roll, the 1949 musical version uses an unformed version of the trope, having the protagonist (played by BingCrosby) teaching KingArthur's minstrels to perform big band music.
** The 1989 TV movie version has the protagonist impressing the court with rap music from her boom box.
** ''AKidInKingArthursCourt'' has basically the same scene, with the boom box replaced with a Discman.
** In ''BlackKnight'', Martin Lawrence wins over the king by teaching the court musicians to play Music/SlyAndTheFamilyStone's "Dance to the Music" on medieval instruments in a matter of minutes. Naturally, the musicians pick this up with very little prompting, and naturally, it gets everyone in the court up and dancing.
* In the movie ''Film/CrusadeInJeans'' (but not the book), [[TheProtagonist the time-traveling protagonist]] carries a walkman that he tries to use to seduce a local girl. This backfires because he puts in a tape of heavy metal music, rather than romantic melodies. Later, he uses it to bribe a merchant; this works out just fine.
* Parodied in ''AustinPowers: The Spy Who Shagged Me'', where Dr. Evil plays Joan Osborne's "One Of Us" for his cohorts back in the '60s and claims he put it together himself.
* ''Film/StarTrekFirstContact'' has a weird inversion, where rock 'n' roll is a nearly-forgotten historical curiosity to the ''Enterprise'' crew, but is still alive and well in the era they travel back to. "Magic Carpet Ride" by Music/{{Steppenwolf}} is featured prominently.
** It's weird to think that a movie in the 1990s about people from the 2370s in the 2060s who hear a song from the 1960s caused that song to be a belated hit in the 1990s.
* Played straight in the popular Soviet film ''[[IvanVasilievich Ivan Vasilievich Changes His Profession]]'', where two guys from 70s Moscow end up trapped in Tsar Ivan the Terrible's court, while the tsar himself is trapped in the 20th century. One of the characters decides to liven up a medieval feast by getting the minstrels to play along with his singing a popular 70s Russian song (which he does very well). Everybody gets down with it, including the tsar's wife and her ladies-in-waiting. Nobody even notices when the singer takes out a pack of Marlboro for a smoke.
* It's [[HipHop hip-hop]] instead of rock in ''Film/HotTubTimeMachine'', wherein Nick, after performing his cover of Rick Springfield's "Jesse's Girl", wows the audience with his rendition of [[spoiler:"Let's Get it Started" by BlackEyedPeas]].
* Reversed in ''LeningradCowboysGoAmerica'': When the Leningrad Cowboys arrive in America after having been advertised and sold as an American band, it becomes clear that they know nothing about rock and roll... or country or hard rock or any other kind of Western music. They have to teach themselves just about everything on their way through the States, depending on where they are.
-->"Your music will go over big down there. Here we have somethin' different. It's called rock and roll."
* In ''Film/TheSmurfs'', Patrick Winslow introduces the time-traveling Smurfs to a little something called GuitarHero. They even bring the music style back to their own time and Brainy forms his own band called the Brainiacs.
* The time-travelling protagonist of 1993 sequel to ThePhiladelphiaExperiment doesn't actually bring rock to the alternate Nazi-run America, but its absence is indirectly noted. The main bad guy is introduced as he tries to decide what background music to use for a propaganda film celebrating 50 years of totalitarian rule. After listening to Mahler, Wagner, Strauss, and Handl, he decides that "highbrow Eurotrash" won't cut it. Later on, he settles on country swing, but it still doesn't sound quite right.

[[/folder]]

[[folder:Literature]]
* Creator/StephenKing's ''Franchise/TheDarkTower'' series has a few examples of the ancient oldies version with "Hey Jude" being a popular bar song in a post-apocalyptic world, and the drum beat Z.Z. Top's "Velcro Fly" driving the residents of an otherwise abandoned city insane.
* ''{{Everworld}}'':
** When the kids first enter Everworld and bump into Vikings, they impress them with "Killing Me Softly" and a version of "The Battle Hymn of the Republic" with Viking related lyrics.
** Another example is seen in the ninth book. When Anica became allied with the Amazons, she taught them several late-twentieth century songs. This may have worked to her disadvantage, however, as the Amazon leader singing "R-E-S-P-E-C-T" was enough to tip off Anica's witch daughter that she was alive and nearby.
* {{Subverted}} in EricFlint's ''Literature/SixteenThirtyTwo'', the "uptimers" from Grantville(a contemporary West Virginia mining town sent back to the year 1632) hold the Spanish army at bay by playing various recordings on an amplifier, ranging from {{Beethoven}} and {{Mozart}} to BonJovi.
[[/folder]]

[[folder:Live Action TV]]
* In the pilot movie of ''[[BuckRogers Buck Rogers In The 25th Century]]'', 20th Century Buck loosens up a futuristic formal dance by introducing the uptight future humans to "something kinda funky." He teaches the keyboardist to play it simply by snapping his fingers a few times and telling the musician to "let yourself go."
* In ''GoodnightSweetheart'', Gary makes a name for himself as a songwriter by performing [[Music/TheBeatles Beatles]] hits during the Blitz.
* The American version of ''Series/{{Life On Mars|2008}}'' has Sam Tyler (2008 policeman stuck in 1973) impress some cool black New Yorkers by rapping a imperfectly remembered rendition of [[Music/VanillaIce Ice Ice Baby]].
* ''Series/DoctorWho'':
** Mildly {{lampshaded}} in "The Doctor Dances". In WWII, when the nanogenes restore young Jamie from gasmask-zombie to human, the Doctor lifts the boy up, joyously announcing, "Welcome back, Jamie! Twenty years to pop music, you're gonna love it!"
** {{Subverted}} in an early William Hartnell episode. From the way the others had been describing them, Vicki (who is from TheFuture) is surprised to hear the Beatles playing what she considers to be "classical music."
** In [[Recap/DoctorWhoS27E2TheEndOfTheWorld "The End of the World"]], Britney Spears' "Toxic" is referred to as a traditional ballad, and Soft Cell's "Tainted Love" as classical music in the year 5 billion.
* ''Franchise/StarTrek'':
** A non-time-travel variation; in ''Series/StarTrekVoyager'', the titular ship encounters an alien race that feel themselves superior to them--until they hear the Doctor singing, and are entranced. Evidently the aliens never developed the concept of music during their history, and were amazed to discover that simple harmonic arrangements of sound and beat could be so pleasing.
** Played straight later with the aliens hating jazz music and eventually abandoning the Doctor's classical opera style for "music" that consists of nothing but a intrinsically complicated series of sounds that are just confusing if not outright awful.
* In ''Series/BeingErica'', Erica time travels back to her university days in the (early) 90s. As she long forgotten her poetry assignment that she was supposed to read in from of the class that that day, she started to recite the lyrics to "Hit Me Baby One More Time". The cynical literature prof was quite impressed.
* Non-time-travel example: at one point in the miniseries ''[[TheTenthKingdom The 10th Kingdom]]'', Virginia, trapped in a rural part of a a fairy-tale world, must compete in a singing contest wherein all songs must relate to sheep and shepherding. She chooses "We Will Shear You", in the style of Queen's "We Will Rock You".

[[folder:Video Games]]
* ''BrutalLegend'' is practically built around this {{trope}}. Though, with a twist: [[spoiler:Heavy Metal actually came *before* the time Eddie travels to, but was lost to the ages. Eddie actually comes from the future, where it has been re-discovered, and brings Metal back.]]
* In ''VideoGame/HaloCombatEvolved'', the video from the helmet camera of the dead marine shows one soldier complaining to Sergeant Johnson why they have to listen to "the old stuff"--rock music known as Flip Music InUniverse--while on the transport to their target zone. Johnson gives them a pep talk about how it's an important part of Earth's history and culture.
[[/folder]]

[[folder:Web Comics]]
* ''ScaryGoRound'' has Shelley become famous in 1840 by [[http://scarygoround.com/index.php?date=20041021 singing Beatles songs]].
* {{Wereworld}} has Emerson introducing rock and roll to a Anthromorphic/Human Planet.
[[/folder]]

[[folder:Web Originals]]
* ''EnginesOfCreation'' features several instances of modern music being introduced to a medieval society.
[[/folder]]

[[folder:Western Animation]]
* In the ''WesternAnimation/DuckTales'' episode "Time Is Money", Huey, Dewey, and Louie wow prehistoric "caveduck" Bubba with the [[TheEighties Eighties]] "tunes" they [[TimeTravel brought back in time]].
* Inverted in ''WesternAnimation/{{Futurama}}'': when Bender and Leela find Fry in his apartment watching TV and playing Sir Mix-A-Lot's "Baby Got Back", Leela insists he can't spend all his time sitting around listening to classical music. Bender later refers to said music as "StuffyOldSongsAboutTheButtocks."
* {{Averted}} in "Journey Through Time", a particularly trippy episode of {{Jem}}. The Holograms are unknowingly sent back in time by Eric's goon, Techrat. They visit Mozart's period and Woodstock without even getting a song in, but they do a swing song in 1941 London.
* An alien girl sends WesternAnimation/TheBeatles to a distant planet in the episode "Day Tripper," where their playing of the song has the inhabitants dancing among the rock formations.
[[/folder]]

[[folder:Real Life]]
* Played straight by the [=GIs=] who imported American music to Germany in [[TheFifties the 50s]].
* In October 1981, JeanMichelJarre was the first contemporary Western musician ever to play in the People's Republic of China. The Chinese audience had only just been introduced to Jarre's music (and ''any'' modern Western music, for that matter because Jarre's albums ''Oxygène'' and ''Equinoxe'' were the first Western music albums available in China thanks to the British Embassy), and they had never in their lives heard electrically amplified live music before, let alone synthesizers. All they had in Mao's times was classical Chinese music and military marches.
* Not just a music trope: many sports, such as baseball and basketball, have been exported to other countries because of soldiers or missionaries.
* The LeningradCowboys used to parody this at their concerts as one can hear on ''Live In Prowinzz''. They announced to play a style of music that may be unfamiliar to the audience called rock & roll; the current number one rock & roll song in America, to be more specific, which has been number one for seven years already. And then they played Russian folk, for example "Katyusha". Then again, that was in a time when the LeningradCowboys referred to themselves as "the worst rock & roll band in the world".
