Byrd became increasingly attracted to radical politics, and became a member of the Communist Party, explaining that it was "the one group that had discipline, an agenda, and was willing to work within the existing institutions to educate and radicalize American society." He left UCLA, but continued to stage performance art events, albeit on a reduced budget. After their personal relationship broke down in 1966, Moskowitz returned to New York, but she and Byrd stayed in contact. In early 1967 Byrd started to form a rock band with another politically radical composer, Michael Agnello, together with Moskowitz, bassist Stuart Brotman (previously of Canned Heat and later of Kaleidoscope), and African drumming expert Craig Woodson who had also been involved in the New Music Workshop. Audition recordings by this version of the band, from September 1967, are included on some later CD reissues. However, Agnello left the project on a point of principle when a commercial recording contract with Columbia Records was being considered, and Brotman also left.
