Easily one of the trippiest albums in Expo '70's discography, Surfaces comes at you slithering an dreamy. The fake BYG/Actuel artwork might have you believe this is one will explore wild free-jazz territory, but Wright is quite true to his krautrock influences and Surfaces comes off sounding like the festering mutant bastard son of a Harmonium/Cluster union. Practically every song is drone based, but there are a few exceptions like the spastic acoustic vs. fuzzed-out-of-your-brains electric guitar solo of Prelude To Electric Wilder Beasts (unfortunately, I find this song a bit too sloppy to be enjoyed to it's fullest). It's the "shorter" tracks that stand out on this album; like the early Klaus Schulze vibe of Who Left The Door [...]? or the dark mood of Taikong. Fans of early/experimental Moog compositions will absolutely love this one, as will fans of Boards Of Canada (Matroshka Experiment is quite similar to some of their "filler" tracks).
