Arcade Fire (known unofficially as Us Kids Know) is a self-titled extended play (EP) by the indie rock band Arcade Fire.
 The EP was recorded in Maine, United States, during the summer of 2002.
 "Arcade Fire" was remastered and repackaged for its 2005 re-release by Merge Records for fans after they had "grown obsessed" with the band's debut album, "Funeral".
 It was initially released in 2003 by the band at their shows and website, and then re-released in 2005 by Merge.
 It received positive reviews from music critics, although some of them noted that it was inferior to their debut album "Funeral".
 Lyrical themes of "Arcade Fire" consist of parents, suburbia, new love, dread, and drama.
 The EP's third track, "No Cars Go", was re-recorded for Arcade Fire's second full-length album, "Neon Bible".
 No Cars Go has been played at the majority of live shows since the EP release.
 Arcade Fire have also played other songs from the EP, live on every tour since.
 However it has become less frequent.
 On their most recent tour, for "Reflektor", they notably performed Headlights Look Like Diamonds.

 The B-side to the album is a recording of the song "My Buddy" by swing musician Alvino Rey.

Bell Orchestre is a six-piece instrumental band from Montreal, Quebec, Canada.
 In late 2003, they recorded their first album, at the same time and in the same studio that Arcade Fire recorded "Funeral".
 However, Arcade Fire's popularity was just beginning to break when they asked Bell Orchestre to tour with them in the fall of 2005, delaying the release of their album.
 Regarding finishing the album, Bell Orchestre said: "We regrouped and we did this residency at an arts center in Canada in the mountains.
 We actually finished [the record] there, we did a few overdubs and went home and sequenced it and mastered it."
