Remastered 180-gram vinyl. This recording has been specially re-mastered in the US for this vinyl edition from the original tapes. 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 it's striking cover artwork, which depicts Monk as a French Resistance member in a particularly messy attic. Music On Vinyl is especially proud to announce that this recording has been specially re-mastered in the US for this vinyl edition from the original tapes.
