They aren't from the land of ice and snow.

Led Zeppelin singer still admires classic song’s construction, but isn’t sure of his own contribution.

Singer describes titling of 1971 LP as a “kind of Spinal Tap thing.”

The thunderous backbone to Led Zeppelin’s sound went silent when John Bonham was found dead Sept. 25, 1980, ending the band as an active unit.

Pop star delivers “Black Dog” and “Comfortably Numb” at radio festival.

Late singer recalled 1969 performance to 400 people, and 1978 event to 30,000 in previously unpublished interview.

Rock = speed.
