Percy Sledge will forever be associated with "When a Man Loves a Woman," a pleading, soulful ballad 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.
