Thelonious Monk, considered one of the greatest Jazz pianists of all time, recorded Underground in ’67-’68. It’s the last recording with the Thelonious Monk Quartet (Larry Gales on bass, Charlie Rouse on tenor sax, and Ben Riley on drums) and one of the last album he made for Columbia.

What makes Underground special is that unlike his other Columbia recordings, four out of the seven songs were newly composed and recorded. Not to mention its striking cover artwork, which depicts Monk as a French Resistance member in a particularly messy attic.

For this edition of Underground, the recording has been specially remastered from the original tapes in the US.
