Recorded at Chappell Studios in London Nov 15th, 1971 but not released until the late 80s on Black Lion, these recordings are from near the end of his recording and performing career. Monk’s joined by Al McKibbon on bass and Art Blakey on drums.

There are at least 3 volumes in the London Collection as well as a three CD Complete London Collection put out by Black Lion.

My copy—via a private sale—is the 2016 reissue by Org Music on Black Lion labels, pressed at Pallas.
