Heldon was continuing to evolve rapidly. Thanks to the increased presence of drummer Fran?ois Auger and synth / Moog man Patrick Gauthier, Pinhas' project had solidified into a harder and heavier unit. Despite its often warm and near-funky feel, Interface has been cited as an influence on key industrial and noise musicians including Wolf Eyes and Merzbow. 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.
