A good jazz trio is a thing of beauty. But it can also be a thing of redundancy, given how so many of them are just piano, bass, and drums, and how, for every Red Garland Trio or Keith Jarrett / Gary Peacock, Jack DeJohnette team-up, you have sixty-seven others who add nothing new. Which is why I got excited by Seven pieces / about an hour / saxophone, piano, drums (CD, digital), the first album by the trio of saxophonist Mark Reboul, piano player Roberta Piket, and drummer Billy Mintz. Yes, a bass-less trio. Color me intrigued.
