This carnival ride to the netherworld of the soul is PJ Harvey's most dizzyingly radical work since the raw pulse and grind of her 1993 debut. It's also entirely different. Harvey's created an emotionally fractured Gothic fairytale that rides on her spare, tattered piano playing and her voice, which she turns into a fragile siren's call: high, airy, and imperiled, and made otherworldly by a labyrinth of echo. Instead of pop tunes, Harvey offers an 11-song cycle that's the metaphorical story of a breakup in which the Devil, a drug-induced nightmare, and a seemingly bottomless pit of despair all play a part. At the end, in "The Mountain," her banshee wails conclude a journey so oblique it's worthy of David Lynch or Neil Gaiman. Flood, who co-produced Harvey's 1998 epic rock breakthrough Is This Desire? with her, reprises that role, but White Chalk is more chamber music--and a dark chamber at that. --Ted Drozdowski
