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 (lead vocals, guitar); he wrote all but three tracks, with additional composition by members Roger Waters (bass, vocals), Nick Mason (drums), and Richard Wright (keyboards, vocals). 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". The album was recorded at EMI Studios in London's Abbey Road from February to May 1967 and produced by Norman Smith. It blended Pink Floyd's reputation for long-form improvisational pieces with Barrett's short pop songs and whimsical take on psychedelia. The album made prominent use of recording effects such as reverb and echo; employed tools included EMT plate reverberation, automatic double tracking (ADT), and Abbey Road's echo chamber. Part-way through the recording sessions, Barrett's growing use of the psychedelic drug LSD saw his mental state become increasingly debilitated, leading to his eventual departure from the group the following year. The album title was derived from referencing the god Pan in chapter seven of Kenneth Grahame's 1908 children's novel The Wind in the Willows, a favourite of Barrett's. The album was released to critical and commercial success, reaching number 6 on the UK Albums Chart. In the United States, it was released as Pink Floyd in October on Tower Records with an altered track listing that omitted three songs and included "See Emily Play".
