The Epsilons
Philadelphia crooner Lloyd Parks (later of Harold Melvin & the Blue Notes fame) merged with friends Gene McFadden and John Whitehead in the mid-1960s to form the Epsilons. The group was managed by Soul Singer Otis Redding and were soon signed to the Stax Records label. They toured for two years with Redding and backed label mate Arthur Conley on his 1967 hit, "Sweet Soul Music." The single reached No.2 on both the Billboard Hot 100 and Billboard R&B charts. The group disbanded following the tragic death of their mentor Otis Redding.
