It's remarkable just how far DJ and producer Danger Mouse has come since his early, overlooked days with rapper Jemini on Warp off-shoot Lex Records. Back when his fanbase consisted largely of alternative hip-hop aficionados, it was a surprise to see the unassuming New Yorker hitting the headlines with his audacious bootleg release, The Grey Album. Since then, of course, production for Gorillaz has taken him yet closer to the commercial mainstream, but nobody could have anticipated the Gnarls Barkley phenomenon.

If you've heard the warmly soulful lead single Crazy - which we're sure you have, many, many times - then you'll already know how fruitful Danger Mouse's collaboration with singer/songwriter/producer (and Goodie Mob member) Cee-Lo can be. Luckily, this isn't a one-off - St Elsewhere is a remarkably varied album, packed with colliding ideas that inevitably miss the mark once or twice but that, on occasion, create something astounding. Whether dipping into bouncy pop-rock with a cover of The Violent Femmes' Gone Daddy Gone or indulging in ghoulish theatricality on The Boogie Monster and Necromancing, Cee-Lo's vocals provide the most perfect companion for Danger Mouse's studiously vintage production that we've heard to date.

Second single Smiley Faces is the closest you'll get to a Crazy Pt II, while those looking for something a little closer to the Danger Mouse & Jemini hip-hop material will find the dreamy Feng Shui and the wryly comic, bass-heavy Who Cares reminiscent of that earlier sound. Elsewhere, the spirit of DJ Shadow seems to pervade Danger Mouse's deftly layered samples, at once soulful, cinematic and moody, as on Just A Thought, which combines a distorted clatter of stammering drums with Spanish guitar and menacing bass.

Unless you're expecting a flawless album of laid-back summery soul all in the same vein as Crazy, you'll find St Elsewhere a real treat - kaleidoscopic in its diversity and a testament to the duo's accomplished musicianship.
