Erik Griswold – Wolf Moon (Room40, digital) 

Music for 16... detuned pianos!? Yup, that’s right. On »Wolf Moon«, Erik Griswold layers 16 40-minute recordings of improvisations on the pianos housed at the Piano Mill in Willsons Downfall, Australia. The result sounds like a single aleatoric super drone, as if Lubomyr Melnyk and Steve Reich had teamed up for one megalomaniac project.
