About Amanda Palmer:
Amanda MacKinnon Gaiman Palmer is an American singer-songwriter who first rose to prominence as the lead singer, pianist, and lyricist/composer of the duo The Dresden Dolls. She has had a successful solo career, is also one-half of the duo Evelyn Evelyn, and is the lead singer and songwriter of Amanda Palmer and the Grand Theft Orchestra.
I think performance art comes from a simple place of wanting to express things beyond just sound.
