Black Sabbath's Geezer Butler has revealed Tony Iommi cancer diagnosis gave them a 'kick up the rump'.
Earlier this month the guitarist, aged 63, revealed to fans last week that he has been battling the early stages of lymphoma.
Geezer Butler has now said that the band have relocated to the UK to record their new material while Iommi undergoes treatment.
He wrote on his official website Geezerbutler.com: "Today [January 19] we got the engines back up and running at Tony’s home studio. Far from being down and depressed about his lymphoma diagnosis, Tony had already written the music for two new songs, and I must say it has given us all a kick up the rump- it’s great to hear him churning out those riffs again, assuaging the Demon C. Takes more than that to stop Tony. Can’t wait for you all to hear our workings, it has been great working on this stuff."
He continued: "I want to thank the lovely encouraging emails sent to this site giving Tony love and encouragement and great vibes. It really does help, not only Tony, but us as a band- it raises up our spirits and restores our faith in this tarnished world."
Black Sabbath are set to headline next year’s Download Festival on June 10.
The original line-up of the band - Ozzy Osbourne, Tony Iommi, Bill Ward and Geezer Butler - announced at a press conference last year that they will reunite for new material and a world this year.
