In August 1979 Led Zeppelin played two Saturdays at Knebworth Park, their last British concerts with John Bonham, before In Through the Out Door hit the shops.
On 8 November 1971 Led Zeppelin released an untitled Atlantic album tracked mostly at Headley Grange, with four symbols on the sleeve and Stairway to Heaven in the middle.
Riffs and Beats finds John Bonham on an empty arena drum riser, back to the lights, sticks loose in both hands over a kit that still looks too big for anyone else.
