The fifth studio album from these British trip-hop pioneers suggests a dream sequence set in a posh club, delivering meticulously fabricated electronica full of whispery vocals and cushy synths. Tracks like "Joy Factory" a blend of busy drums and sci-fi sound effects, give off a dark, sleek vibe that gets old by album's end. Night is best when it rocks (witness "The Answer" an arena-ready stomper) or when a guest knocks it out of the park: Austin psych band The Black Angels help out on the very strong "Natural Selection" which mixes up futuristic trans-pulse with an earnest, richly harmonized tune that seems nicked from lost Sixties gem.

“Oh Sherrie”

Steve Perry's girlfriend Sherrie Swafford was actually in the studio when Perry began writing this song--his lone Top Ten hit as a solo act--with two co-writers. The trio began at midnight one night with just "Oh, Sherrie!" and "hold on, hold on." Three hours later, they had a complete song. Swafford, however, had to wait until the next day to hear it. "Sherrie actually got tired and went to bed," Perry said. She also appeared in the video, but their relationship did not hold on for long.
