“Underground” is a 1968 LP by Thelonious Monk, notable for its diverse and rare time signatures.
Although this album is most widely-known for its provocative cover image, which depicts Monk as a fictitious French Resistance fighter in the Second World War, it contains a number of new Monk compositions, some of which only appear in recorded form on this album.
This is the last Monk album featuring the Thelonious Monk Quartet.
