From the ‘40s until his death in 2008, reedist Jimmy Giuffre quietly revolutionised the sound of jazz. He originally wrote his swinging standard “Four Brothers” in 1947 when he was a member of Woody Herman's Big Band, but on his own he pursued a singular strain of chamber jazz, often dispatching drums to underline a sublime kind of melodic interplay. His late-‘50s trio with guitarist Jim Hall conveys buoyant joy on “The Train and the River”; a different lineup from 1961 featuring pianist Paul Bley established a pensive beauty that melded the openness of free jazz with pin-drop quietude on Carla Bley's exquisite “Jesus Maria”.
