Diamanda Galás

Diamanda Galás (born August 29, 1955) is an American musician, singer-songwriter, visual artist, and activist. Galás has attracted the attention of the press, particularly for powerful soprano sfogato voice and unorthodox vocal techniques. Her work has ranged from highly experimental work for solo voice, to more conventional interpretations of popular music accompanied by her own piano.

She has been describe 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".

Galás has presented mainly her own work, but her live performances have also included works by other musicians, such as the avant-garde composers Iannis Xenakis and Vinko Globokar, jazz musician Bobby Bradford, saxophonist John Zorn, and Led Zeppelin bassist John Paul Jones. Galás's recordings have also included collaborations, some of which are with the bands Recoil and Erasure, instrumentalist Barry Adamson, and musician Can Oral (also known as Khan), among others.
