In addition to archival footage of Dio from throughout his life, the event will feature guest performances, interviews, and birthday wishes from Tony Iommi, Dio and Black Sabbath drummer Vinny Appice, Lita Ford, Glenn Hughes, Anthrax’s Joey Belladonna, and Testament’s Chuck Billy, among many others. It will take place on RollingLiveStudios.com at 5 p.m. ET.
The charity, which is selling merch associated with the event, will be offering signed copies of Rainbow in the Dark: The Autobiography, which Dio wrote with his widow and manager Wendy Dio and journalist Mick Wall, for sale on July 27th.
The livestream will feature appearances from Carmine Appice, Michael Angelo Batio, Gilby Clarke, Aynsley Dunbar, Jeff Pilson, Rudy Sarzo, Lajon Witherspoon, and others. Participating Dio band members include Simon Wright, Oni Logan, Scott Warren, Bjorn Englen, and Rowan Robertson. Dio producer Wyn Davis and Wendy Dio will also sit for interviews.
Since its foundation in 2011, a year after Dio’s death, the Cancer Fund has raised more than $2 million for cancer research.
Iommi recently reflected on Dio’s time in Black Sabbath in a Rolling Stone interview. “I’d heard Ronnie when Ritchie [Blackmore] put out the first Rainbow album [after he left Deep Purple],” he said. “Obviously, you’d say, ‘I wonder what Ritchie’s band’s like.’ I liked the album, and of course, I loved Ronnie’s voice, not thinking for a minute we’d ever end up together. He’s always had a real strong, powerful voice.”
