Led Zeppelin were an English rock band who formed in 1968. With their heavy, guitar-driven sound, Led Zeppelin are regarded as one of the first heavy metal bands. Their rock-infused interpretation of the blues also incorporated rockabilly, funk, jazz, and many other styles of music. The band did not release the popular songs from their albums as singles in Britain, as they preferred to develop the concept of album-oriented rock.Over 25 years after disbanding after John Bonham's 1980 death, Led Zeppelin continue to be held in high regard for their artistic achievements, commercial success, and broad influence. The band have sold more than 300 million albums worldwide, including 109.5 million sales in the United States. They also continue to reunite and tour periodically.
