Röyksopp's debut disc, Melody A.M., produced mood-setting mix-tape fodder and soundtracked any room at a rave that came with a couch. The Understanding starts in the same vein, with parochial piano and a gentle percussive pulse, but then it turns the beat around, disco-style. Bop-gun bloops, vocoder murmurs, quick-click drums, handclaps, an awestruck-choir effect, a sampled dude yelling "yeah" -- all these elements appear during up-tempo numbers. The Norwegian duo enhances its airy vocals with supplementary singers; Chelonis R. Jones adds R&B flava, Kate Havnevik wails in dance-diva fashion, and Karin Dreijer describes "flashlights and explosions" in a wide-eyed warble. The record's centerpiece is the eight-minute "Alpha Male," which sprawls like a '70s prog suite right down to the flute solo. Opening with an ambient yawn and keyboard-generated horn fanfare, the song evolves into a techno thumper with an elastic "Humpty Dance" bass line, then fades back into hibernation mode. It plays like a single-song career study, merging the group's somnolent origins with its groove-driven present, and the stark contrast flatters the latter. Röyksopp's chill-out approach had its charms, but its fast-paced material is a lot more fun.
