FORCES IN MOTION: THE MUSIC AND THOUGHTS OF ANTHONY BRAXTON by Graham Lock

Da Capo Press, 1989 First edition, 412 pp., 5 1/2" X 8 1/2", Softcover

Very good

Forces in Motion is at once a kind of road journal of Braxton's quartet as they toured England in the early 80's, and a highly detailed exposition of Braxton's philosophy of music and the universe.
