Ondulation

Clearly, Moebius is a legend & Lifetime Achievement Award-winner - for his work in Cluster & Harmonium, his collaborations with Eno & an epic solo career that's still going strong (he & Roedelius were touring as Cluster just this autumn, I'm mortified to discover from his site...).

Anyway, see a good overview of the great man's output at All Music Guide & check out the satisfyingly throbbing, echoey, spacey Ondulation from 1999's Blotch (buy here).
