The tapes of these two 1964 San Francisco shows stayed locked up at Columbia Records until the label drew a double-LP from them shortly after Monk's death in 1982. Never issued on CD in the U.S., that album is now superseded by this packed document that nearly doubles its length, restores edited portions of several performances, and adds a dozen performances that sometimes better the original recordings. Monk, saxophonist Charlie Rouse, bassist Larry Gales, and drummer Ben Riley are unsurprisingly on point for the dates, which are filled with numerous classics from the Thelonious book.
