A revolving New York City collective led by Dave Derby, Gramercy Arms displays a diverse, breezy power-pop inspired indie rock center -- not unlike Derby's most famous band, the Dambuilders -- with a tendency to shift style from song to song. The initial line-up contained members of Luna, Guided By Voices, Dead Air, while everyone from fellow ex-Dambuilder Joan Wasser (a.k.a. Joan as Police Woman) to Lloyd Cole to comedian Sarah Silverman have been known to add their talents.
