Daniel Carter & William Parker

Bassist William Parker and saxophonist and trumpeter Daniel Carter revisit the duo format they explored to thrilling effect in the late 1970s, as documented on last year's incredible Centering boxset. Carter's anarchist beliefs translate into a cooperative approach to musicmaking, while Parker has explored his engaged vision of art through big band projects, small groups and the annual Vision Festival.
