Sinéad and Fiachra Ó Laoire
Fictional twin Irish avant-garde composers from the 2015 art project Historical Documents of the Irish Avant-Garde by Dr. Jennifer Walshe. They were born in Belfast, 11 June 1890. Fiachra died of tuberculosis on 27 April 1917. Sinéad died in August 1958.
They built their own instruments which they called “ruaillebuailles." One of their compositions is titled “The Death of King Rí Rá” (1910).
They were rediscovered in 1988 and appreciated by Sonic Youth's Lee Ranaldo.
