Roger Keith "Syd" Barrett was an English singer, guitarist and songwriter who co-founded the rock band Pink Floyd in 1965. Barrett was the band's original frontman and primary songwriter, known for his whimsical style of psychedelia, English-accented singing, and stream-of-consciousness writing style. As a guitarist, he was influential for his free-form playing and for employing effects such as dissonance, distortion, echo and feedback.

The Piper at the Gates of Dawn is the debut studio album by English rock band Pink Floyd, released on 4 August 1967 by EMI Columbia. It is the only Pink Floyd album made under the leadership of founder member Syd Barrett ; he wrote all but three tracks, with additional composition by members Roger Waters, Nick Mason (drums), and Richard Wright. The album followed the band's influential performances at London's UFO Club and their early chart success with the 1967 non-album singles "Arnold Layne" and "See Emily Play".
