Similar to their song "Tracy", the track begins with recorded a phone call (which can be heard throughout most of the song) between Stuart Braithwaite and friend David Jack, whilst an electronic drumbeat plays. At (0:18), they are joined by the sound of a Bontempi Organ playing an A♯ major chord, followed by a D minor chord, which is repeated throughout the song. Layers of synth and a guitar riff play over the chords. A whooshing noise can be heard at various points. At (1:56) acoustic drums can be heard playing the drumbeat, until (2:30), when it goes back to electronic drums. At (3:53), distorted guitars begin playing along and feedbacking with the chords in the background. This guitar noise and feedback continues, fading in and out gradually for the next few minutes, until it becomes almost overbearing, at which point the song ends abruptly.
Legacy
The track was one of the earliest singles to bring Mogwai to critical acclaim. "Superheroes of BMX" was an early band name for the English indie rock group Bloc Party.
