''Crush 40'' (formerly Sons of Angels) is a Japanese-American HardRock duo. Best known for their work on the ''SonicTheHedgehog'' video game series beginning with ''VideoGame/SonicAdventure'', Crush 40 consists of Jun Senoue, guitarist and composer who previously worked on ''VideoGame/DaytonaUSA'', ''VictoryGoal'' and numerous other Sega franchises, and Johnny Gioeli, the frontman of Music/{{Hardline}} and vocalist for Music/AxelRudiPell.

Their style has generally fallen under the MelodicRock umbrella, combining uplifting, self-empowering vocals with soaring rock riffs and intense solos. They often use elements of HardRock and HeavyMetal, and guitarist/songwriter Jun Senoue cites many famous rock bands of the 80's as big influences for the group's sound.

They first teamed up to perform the opening theme song "Open Your Heart" for ''VideoGame/SonicAdventure'', then came back together under the moniker 'Sons of Angels' to record the soundtrack for the game ''NASCAR Arcade'', which were all released on their first album, ''Thrill of the Feel''. Soon after the game was released however, the Swedish metal band 'Sons of Angels' reunited, so Jun and Johnny changed their group name to 'Crush 40', combining the name Jun's favorite soda and Johnny's favorite number. ''Thrill of the Feel'''s European release, which came out after the name change, was simply known as ''Crush 40''.

They next appeared on the soundtrack of ''VideoGame/SonicAdventure2'', providing their SignatureSong "Live and Learn". They provided two original songs for the next two games in the Sonic series, ''VideoGame/SonicHeroes''[[note]]The self titled "Sonic Heroes" (the main theme) and "What I'm Made Of" (the FinalBoss Theme)[[/note]] and ''VideoGame/ShadowTheHedgehog''[[note]]"I Am All Of Me" (Main Theme) and "Never Turn Back" (Credits Theme)[[/note]]. They appeared in ''VideoGame/SonicTheHedgehog2006'', recording a cover of fellow hard rock band Music/MagnaFi's "All Hail Shadow" (featured in ''VideoGame/ShadowTheHedgehog'') and covered PunkRock[=/=]PunkRap band Music/{{Zebrahead}}'s theme song "His World". They wrote four songs for ''[[SonicStorybookSeries Sonic and the Black Knight]]'', as well as later doing a cover of Music/AllEnds "With Me", the games final boss music, and providing an in-game unlock-able cover of Music/{{Steve Conte}}'s "Seven Rings in Hand", the main theme of ''[[SonicStoryBookSeries Sonic and the Secret Rings]]''. They also wrote the theme song "Free" for ''[[VideoGame/SonicRiders Sonic Free Riders]]'', and performed their own version which was included on the game's soundtrack. Many of their previous songs appear in ''VideoGame/SonicGenerations'', and they have also recorded their own version of the North American ''VideoGame/SonicTheHedgehogCD'' theme song "Sonic Boom", collaborating with SynthPop group Music/CashCash. They also collaborated with electro house/techno artist Music/CircuitFreq on a remix of "Open Your Heart" used in ''VideoGame/SonicGenerations''.

They have released three albums: ''Sons of Angels'', the ''NASCAR Arcade'' soundtrack; the self-titled ''Crush 40'', which is a repackaged version of ''Sons of Angels'' with the instrumental tracks removed and two new bonus songs; and ''The Best of Crush 40 Super Sonic Songs'', a GreatestHitsAlbum, collecting songs from previous game appearances and providing a few new exclusives, such as covers of ''Un-gravitify'' from ''[[VideoGame/SonicRiders Zero Gravity]]'' and Music/TheCult's perennial hit ''Fire Woman'', as well a new original song titled ''Is It You''. Several other songs were also remastered for the album's release.

In 2010, they performed at the ''Summer of Sonic'' event in London. In 2011, they performed live at the ''Sonic Boom'' event at E3 in Los Angeles in collaboration with Music/CashCash. In July 2011, they performed their first full concert in Tokyo, featuring mainly ''Sonic'' material but also including covers of songs from Johnny Gioeli's previous band Hardline, including ''Hot Cherie'', ''Love Leads the Way'', and ''Everything''. They also debuted a new original composition, ''Song of Hope'', a charity single for those affected by the Japanese tsunami earlier that year. Once again, in 2012 they performed at the ''Summer of Sonic'' event in Brighton.

Plenty of Crush 40's old material appeared as unlock-able music tracks in ''VideoGame/SonicGenerations''. However, while Jun Senoue returned to create a large portion of the game's modern styled remixes, Crush 40 didn't make any new songs for the game nor remix any of their old songs themselves. In 2012 they released a 4-track EP titled ''Rise Again'', comprised of 3 new original tracks as well as the aforementioned ''Song of Hope''.

Three years later, in 2015, they released a new album titled ''2 Nights 2 Remember'', featuring 4 new original songs and a slightly edited-down [[LiveAlbum concert recording]] from March 30, 2014 in Tokyo, Japan.

!Tropes that apply to Crush 40 include:
* AlternativeMetal: "I Am (All of Me)" is this with a bit of an IndustrialInfluence
* AntiHero[=/=]WildCard: "I Am (All of Me)" is sung from the POV of one.
* ArcWords: [[Videogame/ShadowTheHedgehog "I am (All of Me)" and "Never Turn Back"]] have the line "One step forward, two steps back" in their lyrics.
* CallBack: ''Sonic Youth'', one of their newest songs, references old Crush 40 songs in the lyrics.
** [[labelnote:This line,]] "Unleash a million faces, and one by one they fall"[[/labelnote]] from ''I Am (All of Me)'' is a reference to [[labelnote:this line,]] "Like a million faces, I recognize them all, and one by one they all become a number as they fall"[[/labelnote]] from ''What I'm Made Of''.
** "I Am (All of Me)" and "Never Turn Back" both mention the "one step forward, two steps back" metaphor.
* CoverVersion: Tons. Some of their more notable ones are their cover of ''All Hail Shadow'' by MagnaFi (their first cover) and their live cover of Hardline's ''Hot Cherie'', which in itself was a huge case of CoveredUp.
** TheCoverChangesTheMeaning: Their cover of Zebrahead's ''His World''. Originally, it was a fast paced PunkRap song with rebellious and carefree lyrics that perfectly fit Sonic. Crush 40's version was slower paced, and had a more epic feel to it. Its lyrics were mysterious and weighty and more befit Shadow.
*** Their cover of All End's ''With Me'' is much heavier than the original. The tone of the lyrics would also suit Metal Sonic fairly well.
* DarkerAndEdgier: "I Am (All Of Me)", with straight up villainous lyrics, and a more IndustrialMetal sound, to compare to their more traditional metal/ Modern Hard Rock leanings.
* TheEndOfTheWorldAsWeKnowIt: ''Open Your Heart'' seems to be about someone in the middle of such a situation and trying to avert it.
* GratuitousPanning: Their cover of "All Hail Shadow" does this a lot with the guitar parts. During the verses, the prechorus, and the chorus for example, there are two different guitar parts playing at the same time (one on each side). Also, the guitar solo begins with a simple melody on the left side, followed by a similar melody on the right side before going to the middle for the rest of the solo.
* HotBlooded: Many of their songs would not sound out of place in a SuperRobot anime.
* IAmTheBand: Jun and Johnny are the only permanent members, with various people providing other instruments ([[VideoGame/SonicHeroes "Sonic Heroes" and "What I'm Made Of..."]] had different drummers from each other, for example). (The two are prominently featured on the album art for the singles "Rise Again," "One of Those Days," and "Sonic Youth.")
* IAmSong: Most of their songs, actually. Most notably ''I Am (All of Me)''.
* IndustrialMetal: ''I Am (All of Me)'' has elements of this.
* IntercourseWithYou: Their cover of ''Fire Woman'' by Music/TheCult, and ''Hot Cherie'', by Hardline. Which is really odd, considering the [[Franchise/SonictheHedgehog franchise]] the band is normally associated with.
* MarketBasedTitle: Again, ''Crush 40'''s name change from ''Thrill of the Feel''. (Of course, the name change was justified with the band changing its name as well.)
* MetalScream: The version of "Open Your Heart" on ''The Best of Crush 40: Super Sonic Songs'' adds a loud "AAAAAAALLLLLLLLLL RIGHT!" to the intro. The version used for ''VideoGame/SonicAdventure'' and the remix with Music/CircuitFreq in ''VideoGame/SonicGenerations'' do not have this.
* MohsScaleOfRockAndMetalHardness: Usually about a Six (''Live And Learn'' and "His World") or a Seven (''Open Your Heart'', "What I'm Made oF" ) but they occasionally reach higher (''I Am (All Of Me)'' and ''With Me (Massive Power Mix)'') or go down lower (''Is It You'', ''Live Life'')
* MundaneMadeAwesome: "One of Those Days" seems to be about having a bad day.
* NeoclassicalPunkZydecoRockabilly: Their cover of ''His World''. It mixes elements of SymphonicMetal, HardRock, and RapRock, and ends with a random piano solo.
* ShoutOut: "Sonic Youth" is one big shout out to the ''VideoGame/SonicTheHedgehog'' series and its fans. (This was made clear when Johnny pointed this out when the duo performed it at a Sonic Boom convention.)
* SpeedMetal: Their first Sonic song, "Open Your Heart", is in this style, but they abandoned that mostly for the rest of their repertoire. They revisited it in the song "Through the Fire"
* SurprisinglyGentleSong: "Live Life", the ending credits song to ''Sonic & the Black Knight''.
* TitleDrop: In Sonic Youth, a song which has many a CallBack to previous Sonic songs they had written, also drops the line "Crushing 40 all the time."
* VillainSong: "With Me" is this for sure. "What I'm Made Of" could be this, but it depends on interpretation. "I Am (All of Me)" plays with this trope.
