Jimmy Page and Robert Plant recording outside with the Stones Mobile at Stargroves (Mick Jagger's house), England 1972.

"In 1972 I was asked by Jimmy Page to come over to England and record some tracks for a new album. Zeppelin had rented "Stargroves" (Mick Jagger's country estate) along with the Stone's mobile. The tracks that I recorded appeared on two albums, "Physical Graffiti" and "Houses of the Holy". During the sessions we experimented with recording outside on the lawn to try to get a completely neutral acoustic environment devoid of any reverberations. On the song "Black Country Woman" we tracked Jimmy and John Paul Jones playing acoustic guitar. You can hear birds tweeting in the background if you listen carefully…This photo of Jimmy and Robert rehearsing the song was typical of the bands adventurous spirit." ~ Eddie Kramer
