Bolivar Blues was recorded in 1963 in Japan just two days after the concert that produced the Columbia set Monk in Tokyo.  This studio session was created for TV broadcast while Thelonious Monk was touring the country, 

Evidence was part of that same studio session and featured Monk on piano, Frankie Dunlop drums, Butch Warren playing bass and the incomparable Charlie Rouse on sax. Charlie has the uncanny ability to match Thelonious’ unique style note for note!
