Roger Keith "Syd" Barrett (6 January 1946 – 7 July 2006) was an English musician, composer, singer, songwriter, and painter. Best known as a founder member of the band Pink Floyd, Barrett was the lead singer, guitarist and principal songwriter in its early years and is credited with naming the band.
Barrett's innovative guitar work and exploration of experimental techniques such as dissonance, distortion and feedback influenced many musicians, including David Bowie and Brian Eno. His recordings are also noted for their strongly English-accented vocal delivery. After leaving music, Barrett continued with painting and dedicated himself to gardening. Biographies began appearing in the 1980s. Pink Floyd wrote and recorded several tributes to him, most notably the 1975 album Wish You Were Here, which included "Shine On You Crazy Diamond", as homage to Barrett.
