"Whole Lotta Love" is a song by English hard rock band Led Zeppelin. It is the opening track on the band's second album, Led Zeppelin II. The US release became their first hit single. Parts of the song were adapted from Willie Dixon's "You Need Love", recorded by Muddy Waters in 1962; originally uncredited to Dixon, a lawsuit in 1985 was settled with a payment to Dixon and credit on subsequent releases.
Jimmy Page came up with the guitar riff for "Whole Lotta Love" in the summer of 1968, on his houseboat on the River Thames at Pangbourne, England. John Paul Jones has stated that Page's famous riff probably emerged from a stage improvisation during the band's playing of "Dazed and Confused". Page denied that the song originated onstage and that he had the riff and the rest took it from there
