Thomas Edward "Thom" Yorke (born 7 October 1968) is an English musician, singer, and songwriter. He is the lead singer and principal songwriter of the bands Radiohead and Atoms for Peace, known for his use of falsetto. As a multi-instrumentalist, he mainly plays guitar and piano, but also plays synthesizer, bass guitar, and drums among other instruments, and makes use of electronic equipment such as samplers and drum machines; later Radiohead albums credit him with playing "laptop". In the 1990s, Yorke was known as a rock musician, but the 2000 Radiohead album Kid A saw his work expand into electronic music. He has released two solo albums: The Eraser (2006) and Tomorrow's Modern Boxes (2014). Outside music, Yorke is a political activist on behalf of human rights, environmentalist and anti-war causes.
