While he perhaps never achieved star status outside the jazz world, Kenny Drew was and remains one of the preeminent straight-ahead bebop pianists. While he has led a very active career, 1960's Undercurrent was Drew's last album as a leader until the 1970's. In a way, Undercurrent is the intersection of two very popular jazz groups of the day - Cannonball Adderley's (Sam Jones and Louis Hayes) and Art Blakey's Jazz Messengers (Hank Mobley and Freddie Hubbard), with Drew's keys and tunes the unifying voice. Undercurrent is a fine, timeless mix of bop funk, fire, and finesse.
Sash does a great 1998 rendering of this early 70's classic taking up the tempo and adding new drum/percussion tracks. Most of the original elements of the song are left intact. There are two versions from Sash, one being a radio edit which has a different intro and the outro with vocals over the ending.
