Bassist Gary Peacock died September 4th at 85. He was one of those players whose experience spans a vast range; he was a member of Miles Davis’s quintet in 1964, subbing for Ron Carter; that same year, recorded Spiritual Unity with Albert Ayler. He played in a lot of trios, with pianists whose styles were vastly different from each other — Bill Evans, Paul Bley, Masabumi Kikuchi, Marc Copland, Marilyn Crispell — and in the late ’70s became a member of Keith Jarrett’s Standards Trio with drummer Jack DeJohnette. That group lasted from 1983, when they recorded Standards Vol. 1, to 2014, when they disbanded following a farewell concert at NJPAC in Newark, NJ.
