A brilliant moment occurs right at the end of 1977's Interface. The album's final song, its side-long title track, builds up slowly into a roaring tornado of fiercely mutating drum patterns, effervescent synth work, and guitar licks that wail into the atmosphere like an abandoned astronaut. Then, after nearly nineteen minutes of highly futuristic avant-garde space rock, this ultramodern music fades out and is replaced by a concluding few seconds of traditional blues-rock guitar. »We were finishing the track, the tape was rolling, and I started to play a normal boogie or whatever«, remembers Heldon leader Richard Pinhas. »I think it was a good idea to keep it. It just came naturally, at the end.«
