Pianist Bley, bassist Peacock, and drummer Motian enjoy exploring the sounds of their respective instruments. The opening minutes of this CD, from a cut titled "Not Zero: In Three Parts," demonstrate this quite dramatically, as Bley explores some of the lowest notes on the piano, Motian enters with a bang, and Peacock does some plucking on the lowest notes on his bass. Keith Jarrett fans probably recall that Motian and Peacock played in a trio with Jarrett on the ECM CD, "Live at the Deer's Head Inn." Bley is a much different kind of pianist, and this trio sounds quite different from Jarrett's. The music on Not Two, Not One is more exploratory, less lyrical. However, the music here is always musical. These musicians may explore their instruments, but they do not exploit or abuse them. They coax music out of them, sometimes forcefully, sometimes hesitantly, but always convincingly. This is a recording that takes a few hearings to get into, but if you make the effort, you will be rewarded. The recording quality is excellent--clean and full and clear.
