**CD version** Saxophonist Henry Threadgill, bassist Fred Hopkins and drummer Steve McCall originally came together in 1971 as a group designed to play the music of Scott Joplin for a Chicago theatrical production. Air continued as a unit until McCall left the group in 1983. This session from 1977 catches the band at the midpoint of its existence. Three compositions by Threadgill and one each by Hopkins and McCall.
