True to form, Groove Armada does turn in a few keepers, notably the disco track "Easy" and its inspiring reunion with Sixties folk singer Richie Havens, "Hands of Time." But attempted funk-rock anthems like "Purple Haze" and "Madder" come off as contrived and disingenuous, and none of the dance-floor cuts generates as much kinetic heat as previous efforts. Occasionally Lovebox hits its groove, but rarely through the course of an entire song. So maybe it's time for Cato and Findlay to lay off the Cheez Whiz and the nu-metal CDs for now.
