Longtime fans of Deep Forest will be more than a little startled by the initial strains of opening track "Endangered Species," which interweaves aggressive fuzz-guitar riffs with a thunderous, arena-styled backbeat. When did the electro-ambient act become a clique of rockers? Of course, the French act has not completely abandoned the sound of its heyday. There are plenty of fluttering, world-beat-inflected vocals and chants, but there's also a bit of old-fashioned blues that would make more sense on a Bonnie Raitt album than here. The end result is an overall effort that sometimes satisfies and intrigues but often unfolds like a sonic train-wreck. Kudos to the act for experimentation, but demerits for not thinking things through before mastering the material.—LF
