In 1976 George Lewis' association with Muhal Richard Abrams and the AACM led to recordings with Roscoe Mitchell, Anthony Braxton and a tour with Count Basie. Gradually his startling musicianship and the time-honored jazz virtues of a mellow tone and driving sense of rhythm, harnessed to a soaring imagination and technique became known to a growing number of listeners. Lewis came to play at A Space in Toronto his first solo concert and record this album. On "Toneburst (Piece for Three Trombones Simultaneously)", Lewis overdubbed all three trombone parts in the studio. The rest is solo.
