Black Sabbath guitarist Tony Iommi hasn't put out a full length record since Black Sabbath did 13 in 2013, though he did guest on Candlemass' 2019 song "Astorolus – The Great Octopus." Still, it's not like Iommi doesn't have riffs for new music. He's got tons of them.
Iommi told Guitarist that he'd love to do a new project properly, though there would be no touring involved.
“Well, that’s the million-dollar question. I’ve got loads of stuff. I keep saying to Ralph [Baker], my manager, ‘I want to put it down properly,’ but the engineer I’ve used for years, Mike Exeter, has gone on to do other things… I’d like to put some stuff down, but it won’t be a touring band. Actually, Brian May came over and I gave him four or five CDs of riffs, and he’s going, ‘You’ve got to do an album with these, just put them out like that.’ I said, ‘No, I don’t want to do that. I’m going to do them properly.’”
He also discusses potentially having big names join him in the studio for the project like he did for his 2000 solo album Iommi. That album featured such guests as Type O Negative vocalist and bassist Peter Steele, System of a Down vocalist Serj Tankian, Queen guitarist Brian May, Foo Fighters guitarist and vocalist Dave Grohl, and of course Ozzy Osbourne.
“Yes, I’d like that. I sort of did it with the Iommi album in 2000. I had Dave Grohl, Billy Corgan and all sorts of people on it. Another two embarrassing things that I didn’t go for was one where they said, ‘This chap wants to do something. Eminem.’ ‘Who the bloody hell is Eminem?’ I didn’t know, and I went, ‘Oh, no.’ And Kid Rock.
"So I turned a few people down that became quite big later, but I hadn’t the faintest idea. I’d tried to do it before with Planty and a few others, but it was so hard because of management and all that. But the last one, they really wanted to do it, and I enjoyed playing with different people.”
So here's hoping we got an Iommi solo album or something equivalent. Letting Iommi riffs go to waste is considered a sin in most religions.
