Pink Floyd (formed 1965 in Cambridge, United Kingdom) is a British band noted for psychedelic rock and progressive rock music, philosophical lyrics, avant-garde compositions, sonic experimentation, innovative cover art and elaborate live shows. One of rock music’s most successful and influential acts, the group have sold an estimated 73.5 million albums in the U.S., and over 300 million albums worldwide.

Pink Floyd enjoyed modest success in the late-1960s as a psychedelic band led by Syd Barrett. Barrett’s increasingly erratic behaviour eventually caused his colleagues to replace him after The Piper at the Gates Of Dawn with guitarist David Gilmour. (Syd Barrett died on July 7, 2006 of complications arising from diabetes.) The band went on to record several elaborate concept albums; achieving worldwide success with 1973’s The Dark Side of the Moon (The second best-selling album of all time), 1975’s Wish You Were Here, 1977’s Animals, and 1979’s The Wall, among the best-selling, most critically acclaimed, and enduringly popular albums in rock music history. In 1985, singer and bassist Roger Waters declared Pink Floyd defunct. The remaining members continued recording and touring under the name, eventually reaching a settlement with Waters giving them rights to the name and most of the songs.

On July 2nd 2005, the band reunited with Waters for a one time only performance at Live 8 in London’s Hyde Park. It fueled speculation of the reunion becoming permanent, but the band remained quiet for some time. Rumours ran rampant until early that August, when it was reported that Waters had turned down a 150 million dollar deal for a reunion tour. On February 3rd, 2006, Gilmour gave an interview to the Italian newspaper La Repubblica which indicated the band would no longer tour or produce any new material, although various members still plan on producing solo or collaborative material. The possibility of an appearance similar to Live 8 has not been ruled out by either Mason or Gilmour.
