On November 13, 1967, when Pink Floyd performed in Rotterdam, they were on the cusp of significant artistic development. This live recording captures a moment from their early career, shortly after the release of their groundbreaking debut album, *The Piper at the Gates of Dawn*, which had come out earlier that year. The performance is notable as it features Syd Barrett, the band's founding frontman and creative force, during what would be one of his last appearances with the group due to his declining mental health. The setlist includes tracks that showcase the band's early experimental sound, particularly "Set the Controls for the Heart of the Sun," which would evolve into one of their signature pieces. This period was marked by a blossoming psychedelic movement, with Pink Floyd at the forefront, creating a unique blend of avant-garde rock that would influence the genre for years to come.
