AS the title alerts, The Letting Go is yet another change of tack for Kentucky chameleon Will Oldham, alias Bonnie Prince' Billy.

At 35, he packs his backwoods sensibilities in a battered case that he reopens in Iceland, where his baroque music takes on newly expansive expression under the guidance of Bjork producer Valgier Sigurdsson at the Greenhouse in Reykjavik.

The Greenhouse effect is to bring warmth to Oldham's loveliest confessional folk songs yet, each rendered with more tender care and grace than in the past.

Goodbye to spooked Southern Gothic darkness, hello to unexpected pulsing beats on Lay And Love and aching, soulful string quintet arrangements by Ryder McNair and Nico Muhly for Love Comes To Me and No Bad News.

Best of all, Dawn McCarthy, the high and haunting voice of Faun Fables, plays Emmylou Harris to Oldham's Gram Parsons: fragile beauty sublime.
