Teenaged vocalist Tammy Lynn made her music-business debut as a member of Harold Battiste's visionary A.F.O. ("All For One") label collective, one of the earliest African-American-owned record labels in the U.S., which also comprised its own publishing company, At Last. Lynn, a versatile singer with a powerhouse voice, made her first recordings for A.F.O. in 1963, which included the fire-and-brimstone voodoo rocker "Mojo Hannah." After A.F.O. disbanded, Lynn went on to be a much-in-demand backing vocalist, appearing on landmark recordings such as Dr. John's "Gris Gris" and the Rolling Stones' "Exile On Main Street."
