A long-forgotten concert recording of a jazz concert provides some interesting historical insight. “The tapes come from a concert at Carnegie Hall on Nov. 29, 1957, a benefit for a community center. The concert was recorded by the Voice of America, the international broadcasting service, and the tapes also include sets by the Dizzy Gillespie Orchestra, Ray Charles with a backing sextet, the Zoot Sims Quartet with Chet Baker, and the Sonny Rollins Trio. But it is Monk with Coltrane that constitutes the real find. That band existed for only six months in 1957.”
