Wish You Were Here is a concept album by Pink Floyd. Recorded at Abbey Road Studios between January and July 1975 and released on September 15, 1975 (see 1975 in music), the album would later be regarded as one of Pink Floyd's greatest albums and was ranked 209 on Rolling Stone's 500 Greatest Albums of All Time list. Its lyrics, composed by Roger Waters and concerning the music industry, question the market-oriented record companies' lack of understanding and interest for musicians. The album also pays tribute to Syd Barrett, Pink Floyd's former guitarist and chief songwriter, especially "Shine On You Crazy Diamond", and the title track itself.
