British producers Jon Sutton and Barry Jamieson—more commonly known as Evolution—have been making sweet music together since 1987. In the ensuing years, the duo has remixed more than 150 records, recorded a dance-pop cover of Chic's "Everybody Dance," and founded an über-DJ-friendly label (Fluid Recordings). With Unnatural Selection, the beat-smart duo at long last unleashes its debut full-length. And, yes, it's been well worth the wait. Throughout the course of 11 tracks, these brothers in rhythm weave a multi-textured musical tapestry, with ambient nuances washing over sturdy progressive house/trance foundations (witness "Crocodile Man"). The set's lead single, the hypnotic and anthemic "Walking on Fire" (featuring the sublime vocals of Jayn Hanna) is currently nestled in the top 10 of the Billboard Hot Dance Music/Club Play chart; in a perfect world, radio wouldn't be too far behind. Hanna also makes an appearance on the chilled "Making Sense." Sweet surrender, indeed.—MP
