Legendary heavy metal vocalist Ronnie James Dio has revealed during an interview with BBC Radio 2's "Masters of Rock" program that he will once again be collaborating with BLACK SABBATH guitarist Tony Iommi."At this particular point — if all doesn't fall through, and I doubt that it will — Tony Iommi and I are going to write a couple of tracks together for a project that I think is called 'Black Sabbath – The Dio Years'," Dio said. "So that'll be two unreleased tracks which I'm sure will be interesting to old SABBATH fans, and maybe [even] the new SABBATH fans."

Dio recorded a total of three studio albums with BLACK SABBATH — 1980's "Heaven and Hell", 1981's "Mob Rules" and 1992's "Dehumanizer" — in addition to appearing on the classic live album "Live Evil" in 1983. Dio is currently touring Europe with his solo band, which currently includes guitarist Doug Aldrich (WHITESNAKE) filling in for an injured Craig Goldy.
