Some of the songs critique the music business, others express alienation, and 'Shine On You Crazy Diamond' is a tribute to Syd Barrett, whose mental breakdown had forced him to leave the group seven years earlier. Inspired by material the group composed while performing across Europe, Wish You Were Here was recorded in numerous sessions at London's Abbey Road Studios. Wish You Were Here is the ninth studio album by the English progressive rock group Pink Floyd, released in September 1975.
