In 1969, Pharoah Sanders was incredibly active, recording no less than four albums and releasing three. The band on Jewels of Thought is largely the same as on Deaf Dumb Blind and Karma, with a few changes. Idris Muhammad has, with the exception of Hum-Allah-Hum-Allah Hum Allah, replaced Roy Haynes, and Richard Davis has permanently replaced Reggie Workman and Ron Carter, though Cecil McBee is still present for the extra bottom sound.
