Following in his mother's footsteps, Harman took up the drums before he was in his teens and, after a stint in the military, studied percussion in Chicago under Roy Knapp. Upon his return to Nashville, he learned that, contrary to protocol before his departure, artists were now asking for drums on their records. Splitting his time between session work and drumming in a strip joint, Harman played on early recordings by Patsy Cline (including Crazy and Walking After Midnight) and Marty Robbins. Whereas Harman had first taken to using only a snare drum and brushes, by the early '60s he was utilizing a full kit for artists such as the Everly Brothers and Elvis.
Because he was there from the beginning, and in many aspects actually pioneered country drumming within a studio context, Harman has played on several legendary sessions: Roger Miller's King of the Road, Johnny Cash's Ring of Fire, Tammy Wynette's Stand by Your Man, and Roy Orbison's Pretty Woman being just a small list. In 1991, Harman returned to the stool of house drummer at the Grand Ole Opry, a position he originated in 1959. A walking history book of the evolution of Nashville and country music, Harman has played on over 18,000 sessions, making him arguably the most recorded drummer ever. ~ Steve Kurutz, Rovi
