On October 31, 1968, Pink Floyd performed "Let There Be More Light" during the "Tous En Scène" event in Paris, showcasing their distinct sound that was evolving during this period. At this time, Pink Floyd had recently released their second studio album, "A Saucerful of Secrets," which came out earlier that year in June. This album marked a pivotal moment in the band’s career as it was their first full-length release following the departure of founding member Syd Barrett. The live performance underscores the band's transition toward a more experimental and progressive rock direction, integrating complex musical elements and thought-provoking lyrics. Interestingly, "Let There Be More Light" reflects themes of space exploration and consciousness, mirroring the band's growing interest in abstract concepts and advanced soundscapes that would define their later work.
