The latter part of 1975 was a remarkably creative period for Brian Eno. With his masterpiece Another Green World, Eno began moving away from the structure and sound of pop music toward a more static instrumental model, influenced in part by Erik Satie and strongly informed by his prior collaborations with Robert Fripp. Recorded just a month after Another Green World, Discreet Music is his first full foray into what has become known as ambient music. Using the same system of two reel-to-reel tape recorders as No Pussyfooting and Evening Star, Eno was able to layer simple parts atop one another, resulting in a beautiful piece of music that never really changes but constantly evolves with the addition and decay of different parts.
Eno's solo debut, Here Come the Warm Jets, is a spirited, experimental collection of unabashed pop songs on which Eno mostly reprises his Roxy Music role as "sound manipulator," taking the lead vocals but leaving much of the instrumental work to various studio cohorts (including ex-Roxy mates Phil Manzanera and Andy Mackay, plus Robert Fripp and others).
