Percy Sledge will forever be associated with "When a Man Loves a Woman," a pleading, soulful allad he sang with wrenching, convincing anguish and passion. Sledge sang all of his songs that way, delivering them in a powerful rush where he quickly changed from soulful belting to quavering, tearful pleas. It was a voice that made him one of the key figures of deep Southern soul during the late '60s. Sledge recorded at Muscle Shoals studios in Alabama, where he frequently sang songs written by Spooner Oldham and Dan Penn. Not only did he sing deep soul, but Sledge was among the pioneers of country-soul, singing songs by Charlie Rich and Kris Kristofferson in a gritty, passionate style. During the '70s, his commercial success quickly faded away, but Sledge continued to tour and record into the '90s.

While he worked as a hospital nurse in the early '60s, Sledge began his professional music career as a member of the Southern soul vocal group the Esquires Combo. On the advice of local disc jockey Quin Ivy, he went solo in 1966. Ivy fancied himself a record producer and he agreed to help shape Sledge's song "When a Man Loves a Woman" into a full-fledged single, hiring Spooner Oldham to play a distinctive, legato organ phrase. Ivy released the single independently and quickly licensed it to Atlantic Records, who quickly bought out Sledge's contract. "When a Man Loves a Woman" became a huge hit in the summer of 1966, topping both the pop and R&B charts. It was quickly followed that year by two Top Ten R&B hits, "Warm and Tender Love" and "It Tears Me Up," which were both in the vein of his first hit. Although few of his subsequent singles were hits -- only "Take Time to Know Her" reached the R&B Top Ten in 1968 -- many of the songs, which were often written by Dan Penn and/or Oldham, were acknowledged as classics among soul aficionados.
