Selected Ambient Works, Vol. II is a more difficult and challenging album than Aphex Twin's previous collection. The music is all texture; there are only the faintest traces of beats and forward movement. Instead, all of these untitled tracks are long, unsettling electronic soundscapes, alternately quiet and confrontational; although most of the music is rather subdued, it is never easy listening. While some listeners may find this double-disc album dull (both discs run over 70 minutes), many listeners will be intrigued and fascinated by the intricately detailed music of Aphex Twin.
