Volume 1 of Thelonious Monk's complete concert at the Montreal Jazz Festival in August 1965. At the head of his last great quartet featuring Charlie Rouse on tenor sax, Larry Gales on bass and Ben Riley on drums, Thelonious "Sphere" Monk was in top form delivering a strong set of angular tunes including originals such as "Straight No Chaser", "Evidence", "Epistrophy", "Blue Monk" and a rare interpretation of a classic standard like "April in Paris".
