Ronnie James Dio (born Ronald James Padavona; July 10, 1942 – May 16, 2010) was an American heavy metal vocalist and songwriter. He performed with Elf, Rainbow, Black Sabbath, Heaven & Hell, and his own band Dio. Other musical projects include the collective fundraiser Hear 'n Aid. He was widely hailed as one of the most powerful singers in heavy metal, renowned for his consistently powerful voice and for popularizing the "devil's horns" hand gesture in metal culture. He was collaborating on a project with former Black Sabbath bandmates Tony Iommi, Geezer Butler and Vinny Appice, under the moniker Heaven & Hell, whose first and only studio album, The Devil You Know, was released on April 28, 2009. On the morning of May 16, 2010, he died after a six-month battle with stomach cancer. He was 67 years old.
Dio's musical career began in 1957 when several Cortland, New York musicians formed the band The Vegas Kings, which soon changed their name to Ronnie and the Rumblers.
