The album included Barrett's final contribution to their discography, "Jugband Blues". Waters began to develop his own songwriting, contributing "Set the Controls for the Heart of the Sun", "Let There Be More Light" and "Corporal Clegg". Wright composed "See-Saw" and "Remember a Day". Norman Smith encouraged them to self-produce their music, and they recorded demos of new material at their houses. With Smith's instruction at Abbey Road, they learned how to use the recording studio to realise their artistic vision.

The first of several Pink Floyd album covers designed by Hipgnosis, it was the second time that EMI permitted one of their groups to contract designers for an album jacket.

John Peel described a live performance of the title track as "like a religious experience", while NME described the song as "long and boring ... [with] little to warrant its monotonous direction". On the day after the album's UK release, Pink Floyd performed at the first ever free concert in Hyde Park. In July 1968, they returned to the US for a second...
