Famous rock bands of the 1970s include Pink Floyd, Led Zeppelin and Rush. Rock music has constantly changed and redefined itself since its 1940s origins, and these bands are but a fraction of those that gained popularity in the '70s.
Pink Floyd's original band members were performing as early as 1964, but it was the popularity of 1973's "The Dark Side of the Moon" that brought the band to the front lines of rock popularity. "The Dark Side of the Moon" stayed on Billboard's Top 200 album chart for longer than any other album in history at 741 weeks.
Led Zeppelin was an influential heavy metal pioneer. They were formed in 1969 when the Yardbirds dissolved, and their albums gained increasing popularity. The band's 1973 U.S. tour broke box-office records throughout the country, and by 1975, immense ticket and album sales had made Led Zeppelin the most popular rock group in the world.
Rush is a Canadian power-trio from Toronto, Ontario. They released a self-titled album in 1974, after which drummer John Rutsey left the band. It was at that time Neil Peart joined as replacement drummer and took over the role of primary songwriter, creating lyrics influenced heavily by Sci-Fi and fantasy. In 1976, Rush released "2112." The album proved to be the band's breakthrough, and it was the first in a long line of gold and platinum releases. Typically dismissed by critics, Rush won an impressive and loyal fan following, and the band's performance skills solidified their standing as musicians' musicians.
