This song, along with the rest of 13, was helmed by Rick Rubin (Beastie Boys, Red Hot Chili Peppers, Metallica, Johnny Cash). Guitarist Tony Iommi recalled to Guitar World magazine the strange experience of working with the legendary producer Rick Rubin: "I didn't quite know what to make of Rick at first," he admitted. "His whole idea was, 'Write the song. Call me when you think it's ready.' So I would. Actually, I'd email him, because I couldn't phone him – nobody phones him. So I'd email him: 'Do you want to come down tonight?' And he'd pop in, have a listen, go, 'Yeah, I like that,' or, 'I don't like it.'
"We wanted him to be more involved but he was this elusive guy that we never really saw," Iommi added. "But when we started recording, he was there all the time, lying on the bed with the microphone. Blimey, what a strange guy!"
