She’s a founding member of the Scottish alt-pop band Belle and Sebastian. He’s the gravel-voiced singer for Screaming Trees, Soulsavers and Gutter Twins. Together, Isobel Campbell and Mark Lanegan have released a pair of oddly affecting collaborative albums of moody cinematic ballads and ragged Americana: 2006’s Mercury Prize-nominated Ballad of the Broken Seas and ‘08’s Sunday at Devil Dirt. While Lanegan’s distinctive growl became one defining aspect of the albums, Campbell served as the driving creative force, writing and arranging the songs, serving as duet counterpart and producing the sessions. It was clear that Campbell was expected to do what Lanegan referred to as "the heavy lifting."
You Won’t Let Me Down Again is a single from their latest album, Hawk, releasing on Aug 24, 2010.
