Thelonious Monk Quartet Featuring John Coltrane at Carnegie Hall

In early 2005, an engineer at the Library of Congress accidentally discovered, in an unmarked box, the recording of Thelonious Monk's and John Coltrane's performance at a 1957 benefit concert at Carnegie Hall. Long considered one of the most important musical meetings in modern jazz, Monk's and Coltrane's work together during a scant few months in 1957 had, until this discovery, been thought to be almost entirely undocumented.
