The Piper at the Gates of Dawn is Pink Floyd's debut album and the only one made under Syd Barrett's leadership, although he made some contributions to the follow-up, A Saucerful of Secrets. It has been regarded as one of the most influential LPs ever made , being a tremendous influence on the psychedelic rock scene of the time and much of what followed. The album has whimsical lyrics about space, scarecrows, gnomes, bicycles and fairytales, along with psychedelic instrumental passages. The album celebrated its 40th anniversary on 5 August 2007.
