It's P.O.V. and not P.O.W.. Chamber jazz. Lewis takes some wonderful solos as does Richard Davis, bass. Also featured are Mel Lewis, drums, Harold Jones, flute + violin and cello.
If you are at all into what used to be called "Third Stream" (for want of a better description) you will love this album. If you are a John Lewis fan you will love this album. If you like good music without regard to putting a title to it, you will love this album.
