I think this may have been posted before on a blog, but not for some time, so I guess some people don't have it. It was a short-lived quartet, which produced only two recordings to my knowledge, of which this is the second. The quartet, led by alto saxophonist John Tchicai, have a very distinctive sound, never reproduced by any other ensemble. The uniqueness of the sound comes from the collective interpretations of the tunes, rather from any long solos.
It is also interesting to note that all four members of the quartet are still alive and peforming (to my knowledge).
John Tchicai: alto sax
Roswell Rudd: trombone
Reggie Workman: bass
Milford Graves: percussion
