Vinyl LP pressing. Reissue, originally recorded and released in 1957. One of Charles Mingus's lesser-known sessions. Here the master was at the head of an awesome band including some of his regular sidemen. Features Jimmy Knepper (trombone), Shafi Hadi (alto saxophone, tenor saxophone), and Dannie Richmond (drums), along with nothing but Bill Evans on piano. This is dense, lyrical, and very stimulating music deeply rooted in the bop tradition yet with an open ear to other sound territories.
