Gary Rees, the stepson of late Black Sabbath keyboardist Geoff Nicholls, has shared what appears to be a previously unreleased track from Black Sabbath’s Ronnie James Dio-era. Rees said the following about that:

“This latest upload from the Geoff Nicholls estate I believe is called Slapback from the scrawling on the cassette and the chorus. This is from the same cassette as the Heaven & Hell upload on this channel. It doesn’t sound like a typical Sabbath song if it is them but it does sound like Ronnie James Dio. It must be a cover, any clues? I have no idea about anything I wasn’t there. Everything is speculation. Great tune by the way. Is it Ronnie on bass or ‘a friend from Birmingham’?.”
