Born in Lawton, Russell attended Will Rogers High School in Tulsa, Oklahoma, and began his musical career as a session musician, quickly gaining experience and becoming a high-end keyboardist in demand to notable artists from the 1960s to the present.
By the late 1960s, Russell branched out, first to writing songs, and then working his way from gigs as a sideman to joining bands as a full member. Eventually, he moved into a solo recording position, although he never gave up all his previous roles within the music industry.
