Thomas Edward "Thom" Yorke (born 7 October 1968) is an English musician, singer, and songwriter. He is the lead vocalist, lyricist, principal songwriter, guitarist and pianist of the bands Radiohead and Atoms for Peace, known for his falsetto singing style. 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 him expand into electronic music. In 2006, he released a solo album, The Eraser. Outside music, Yorke is notable as a political activist on behalf of human rights, environmentalist and anti-war causes.
