Angle has Barry Guy on bass, Alan Jackson on drums, and on one track, Barbara Thompson on flute. Sort of like a more "composerly" approach to what Bley was doing at the time. Excellent date.
The Ricotti has Chris Spedding on guitar (on fine form), Brian Spring on drums and Chris Laurence on bass. Gary Burton isn't a bad comparison, but this is certainly more ragged around the edges. I like it a lot.
