Wish You Were Here is the ninth studio album by English rock band Pink Floyd. It was released on 12 September 1975 by Harvest Records in the United Kingdom and a day later by Columbia Records in the United States. The album topped record charts in both regions. Inspired by material the group composed while performing around Europe, Wish You Were Here was recorded during numerous recording sessions at Abbey Road Studios in London, England. Two of the album's four songs criticise the music business, another expresses alienation and the multi-part track "Shine On You Crazy Diamond" is a tribute to Syd Barrett. Barrett's mental breakdown had forced him to leave the group seven years earlier, prior to the release of the group's second studio album A Saucerful of Secrets (on which he only appeared on three tracks). It was lead writer Roger Waters' idea to split "Shine On You Crazy Diamond" into two parts that would bookend the album around three new compositions and to introduce a concept linking them all.
