Diamanda Galás is an American musician, singer-songwriter, visual artist, and activist. Galás has attracted the attention of the press particularly for her voice — a soprano sfogato — and written accounts that describe her work as original and thought-provoking refer to her as "capable of the most unnerving vocal terror", an "aesthetic revolutionary", "a mourner for the world's victims" and "an envoy of risk, honesty and commitment".
