Egerton's contributions were primarily instrumental; he wrote the music for "Impressions", "Iceman", "All-O-Gistics", and "Schizophrenia", and co-wrote the music for "Van" and "Uranus". "Stephen harnessed the job of trying to expand some of the melodic boundaries", said Stevenson. "He would kind of come up with what I would call the nasty chords."
