On the recording process, Iommi explained, "We could've continued and gone on and on, getting more technical, using orchestras and everything else, which we didn't particularly want to. We took a look at ourselves, and we wanted to do a rock album –
Sabbath Bloody Sabbath wasn't a rock album, really." According to the book
How Black Was Our Sabbath, "The recording sessions would usually carry on into the middle of the night. Tony Iommi was working really hard on the production side of things with the band's co-producer Mike Butcher, and he was spending a lot of time working out his guitar sounds. Bill, too, was experimenting with the drums, especially favouring the 'backwards cymbal' effect." Osbourne, however, grew frustrated with how long Black Sabbath albums were taking to record, writing in his autobiography, "
Sabotage took about four thousand years." According to Iommi, the
Sabotage sessions were the scene of a legendary jam session between Black Sabbath and
Led Zeppelin. Iommi's recollection may be inaccurate, however, as records show that Zeppelin were
on tour in the US at the time
Sabotage was being recorded. Ward's recollection of the exact timing of the Zeppelin jam session is also fuzzy. "I don't even know what album we were working on", the drummer explained. "But one of
John (Bonham)'s favourite songs was '
Supernaut' – so, when they came down to the studio, he wanted to jam 'Supernaut'." It is more likely that the jam session took place during the recording of the previous album,
Sabbath Bloody Sabbath. ==Composition==
