Pink Floyd is an English rock band formed in London in 1965, recognized as pioneers of psychedelic and progressive rock. Known for their innovative sound, philosophical lyrics, and spectacular live shows, their music is marked by extended compositions and sonic experimentation. The band was originally founded by Syd Barrett, Nick Mason, Roger Waters, and Richard Wright, with David Gilmour joining soon after. Early hits like Arnold Layne and See Emily Play established their reputation, while albums such as The Dark Side of the Moon, Wish You Were Here, Animals, and The Wall became some of the best-selling and most influential records in rock history. After lineup changes and internal tensions, Waters left the group in the mid-1980s, leaving Gilmour, Mason, and later Wright to continue the band. Pink Floyd released landmark albums supported by major tours and reunited on occasion, including a notable performance at Live 8 in 2005. Over their career, Pink Floyd has sold more than 250 million records worldwide and received inductees into both the US Rock and Roll Hall of Fame and the UK Music Hall of Fame. The band’s legacy is marked by enduring hits such as Money, Another Brick in the Wall, and High Hopes, and their influence continues to shape popular and progressive music.
