( heavy metal ) Black Sabbath - Slapback from Heaven and Hell torrent

Tony Iommi recently talked to Guitar World about his five favorite Dio-era Black Sabbath riffs. And while there were obvious inclusions like Neon Knights and Heaven and Hell, one song that didn’t make the electric guitar legend’s list was Slapback, which is likely because until a few days ago, no one even knew it existed.

The song – recorded during the 1979 songwriting sessions that produced Heaven and Hell, the band’s first album with singer Ronnie James Dio – was recently uploaded to YouTube by Gary Rees, the stepson and executor of the estate of Geoff Nicholls, Black Sabbath’s longtime keyboardist, who passed away in 2017.

Following Rees’s YouTube posting, questions arose as to Slapback’s authenticity. But in a new interview with Eddie Trunk on SiriusXM's Trunk Nation With Eddie Trunk, Sabbath bassist Geezer Butler offered confirmation.

"Yeah, that was one of the songs that we did before I left," he said of Slapback.

He added, jokingly, "It's probably the reason I did leave. It was just one of those songs that didn't make the grade."

And while Butler exited Sabbath for a short time before returning for the recording of Heaven and Hell, he also stated that it is his bass that can be heard on the song.

"Yeah, that was right before I left,” he said. “It was just a one-off thing. We just jammed it and didn't think anything more of it. It didn't really work."
