Trembling Blue Stars is a London-based band that currently includes members Robert Wratten and Beth Arzy (who was also in Aberdeen until they split up in 2005). Begun as a side project of Wratten's previous band Northern Picture Library, Trembling Blue Stars became Wratten's main band when Northern Picture Library broke up in 1995. Wratten took the name of his band from The Story of O by Pauline Réage. The Stars are characterized by slow songs with jangly guitars and introspective, painful lyrics.
