Eluvium

Pioneer Courthouse Square, MFNW.  Eluvium is Portland's Matthew Cooper, who takes dense layers of guitars and pianos and builds them into awe-inspiring walls of sound. A simple guitar figure gets repeated into a folk-sounding song, which soon dissolves into echoes, and later whale songs are layered on top of it all before the whole structure collapses into pure ambient sound. Interesting, and interesting that such experimental music held the audience's attention as it did.
