Monk's Blues is an album by Thelonious Monk released in 1968 on Columbia Records. It was recorded in Los Angeles in 1968 and features Monk accompanied by a horn section and arrangements by Oliver Nelson, an unusual approach in his discography.
The album includes original Monk compositions such as 'Blue Monk' and 'Straight, No Chaser', as well as new pieces like 'Monk's Blues'. Nelson's arrangements incorporate blues and big band elements, departing from Monk's characteristic small-group sound.
Produced by Teo Macero, the album received mixed reviews upon release but has been reassessed over time as an interesting experiment. The cover features an abstract painting of Monk.
