Originally issued in two volumes on their own SRP Records in 1966 & 67 as In Concert At Yale University and Nommo, the duo of drummer/percussionist Milford Graves and pianist Don Pullen are heard live in in this excitingly energetic and revelatory concert at Yale University, redefining the roles of their instruments during the most exploratory period of free jazz.

Recorded in 1976 at WBAI-FM/Free Music Store in New York, drummer percussionist Milford Graves goes head to head with two reedists, Arthur Doyle and Hugh Glover, an absolute stunner of percussive momentum and force, drawing the reeds into a frenzy of unbridled free playing; issued with a 2nd CD of a private recording of Graves plus unpublished photos.
