Roger Keith "Syd" Barrett was an English musician, composer, singer, songwriter and painter, best remembered as a founder member of the band Pink Floyd. He was lead vocalist, guitarist and principal songwriter during the band's psychedelic years, providing major musical and stylistic direction in their early work. He is credited with naming the band. Barrett left the group in April 1968 and was briefly hospitalised amid speculation of mental illness exacerbated by drug use. Barrett was musically active for fewer than ten years. He recorded four singles with Pink Floyd, the debut album, plus several unreleased songs. In 1969, Barrett initiated his solo career when he released the single, "Octopus", taken from his first solo album, The Madcap Laughs. The album was recorded over the course of one year with five different producers. Nearly two months after Madcap was released, Barrett began working on his second and final album, Barrett, which was released in late 1970. He then went into self-imposed seclusion lasting until his 2006 death. In 1988, an album of unreleased tracks and outtakes, Opel, was released by EMI with Barrett's approval.
