For any band to follow up on a success is not an easy task, and even in the best circumstances, coming back from the massive success of "Dark side of the moon" could have been an impossible task for Pink Floyd . Unfortunately, when they returned to the studio in January 1975, conditions were far from favorable within the group, for various reasons, in particular the fact that, after having adapted their lives to their worldwide success, the members of the group found themselves more disoriented than satisfied. The problem was made worse by a growing disconnect between bassist Roger Waters and the rest of Pink Floyd, especially guitarist David Gilmour.
