The Dresden Dolls

The Dresden Dolls are an American musical duo from Boston, Massachusetts. Formed in 2000, the group consists of Amanda Palmer (lead vocals, piano, harmonica, ukulele) and Brian Viglione (drums, percussion, guitar, bass guitar, vocals). The two describe their style as "Brechtian punk cabaret", a phrase invented by Palmer because she was "terrified" that the press would invent a name that "would involve the word gothic". The Dresden Dolls are part of an underground dark cabaret movement that started gaining momentum in the early 2000s.
