The never released before historical duets of two of the masters of free improvisation. With cover notes by John Zorn!! "Four decades has not dated these sounds a jot: this is exciting music. Long thought lost, it is an historic meeting of two master improvisers at the very peak of their powers, and sounds just as fresh and modern as the day it was made. This is music that transcends time, style and genre. It is pure. It is real. It is Truth and Beauty." - John Zorn, October 7, 2016-NYC.
