The album was recorded at Clearwell Castle in Wales, near the border with England. Ron Nevison, the band's engineer, made the arrangements. "It was a gothic castle that was opened in the summer for tourists, but in the wintertime, it was closed up and they just rented it out to rock bands to rehearse in," Nevison told Songfacts
. "But where you can rehearse, you can record. So, I went up to have a look at it, and I said, 'Yeah, this would be great.'"
The tape machines and other recording gear were in a mobile recording studio parked outside - the same unit used to record Led Zeppelin's Physical Graffiti
and The Who's Quadrophenia
