As a solo artist, Steve Winwood is primarily associated with the highly polished blue-eyed soul-pop that made him a star in the '80s. Yet his turn as a slick, upscale mainstay of adult contemporary radio was simply the latest phase of a long and varied career, one that's seen the former teenage R&B shouter move through jazz, psychedelia, blues-rock, and progressive rock. Possessed of a powerful, utterly distinctive voice, Winwood was also an excellent keyboardist who remained an in-demand session musician for most of his career, even while busy with high-profile projects. That background wasn't necessarily apparent on his solo records, which established a viable commercial formula that was tremendously effective as long as it was executed with commitment.
