There is a bittersweet coda to this story. In the 2010s, Annette Peacock began to soften. She allowed some of her back catalog onto Bandcamp. Paul Bley passed away in 2016. In 2018, a very limited, expensive vinyl reissue of Dual Unity appeared on the "ECM: Touchstones" series (though Bley was never officially ECM for this album, the aesthetic fits).
In 1963, Peacock entered Bley’s life. She was not just a muse; she was a theorist, a synthesizer pioneer (she was the first vocalist to use a Moog synthesizer as a live instrument), and a composer of staggering originality. She introduced Bley to the concept of "free improvisation with structural intent." Together, they married his spectral piano with her otherworldly, often electronically altered vocals. annette peacock paul bley dual unity blogspot
