The idea came from Andrew Watt. The producer behind Ozzy Osbourne's final two albums, "Ordinary Man" and "Patient Number 9," got to know Tony Iommi while working on Osbourne's records and pitched him on bringing Black Sabbath's original lineup back into the studio. Iommi said no.
He explained why in an interview with Classic Rock: "He was very keen, almost a bit too excited. He didn't really know what it would be like working with the original Sabbath, working with Bill." Iommi also pointed to a more direct reason: "We already did '13,' and I don't like the idea of 'let's do another album.'"
"13" was Black Sabbath's nineteenth studio album, released in 2013 and led by original members Iommi, Osbourne, and Geezer Butler, with drumming duties handled by Brad Wilk of Rage Against the Machine and Audioslave—original drummer Bill Ward sat out due to a contract dispute. The album topped the charts in both the US and UK and earned the band a Grammy for Best Metal Performance. NME gave it three and a half stars at the time, writing that it "gathers together everything you'd expect from a new Black Sabbath album featuring three returning original members."
