After John Coltrane kicked his heroin habit in 1957, he joined Thelonius Monk for a legendary five-month stand at the Five Spot, took a few days out in September to cut his classic Blue Train album and then rejoined Monk's quartet with Ahmed Abdul-Malik and Shadow Wilson for a benefit concert at Carnegie Hall. The Voice Of America broadcast recording was believed lost until just a few months ago, when Library of Congress archivist Larry Appelbaum discovered the tapes of the professionally recorded 51-minute performance, which Blue Note quickly turned into the Carnegie Hall disc. There aren't any shocking set choices among soon-to-be standards like Monk's Mood, Evidence, Crepescule With Nellie and Blue Monk, and the playing is engaging if somewhat restrained (understandable considering the venue). The real interest here is hearing Coltrane effortlessly blowing with such command on Epistrophy and Bye-Ya as he takes his first giant steps toward becoming the leading voice of his generation. A fascinating document.
