Some of the great bassist Gary Peacocks finest music has been made in piano trios. Early in his musical life, Peacock established a fresh role for the bass as an independent melodic voice, a concept carried forward in the history-making groups hes played with from Paul Bleys and Bill Evans trios to Keith Jarretts. He is also an influential bandleader: Tangents, the second, stunning trio release with Marc Copland and Joey Baron, draws on years of shared playing in diverse contexts.
