Richard James (alias Aphex Twin, AFX, Polygon Window, etc.) claims he heard the compositions on Selected Ambient Works, Volume II in lucid dreams. Like abstract paintings composed of shades of a single colour, James's resonant explorations of specific timbres linger close to a central idea on each cut, incorporating just enough variation to remain disturbing. While its predecessor, Selected Ambient Works '85-'92 drew on seven years worth of material, the uniform quality of these untitled tracks, plus their judicious sequencing, suggests they were assembled over a shorter period. Clocking in at over 150 minutes, the double-disc set provides an exemplary introduction to the quieter facets of James's expansive, idiosyncratic aesthetic.
