Dio

Legendary Heavy Metal Vocalist

Dio was a heavy metal band led by vocalist Ronnie James Dio, renowned for his powerful voice and for popularizing the "metal horns" hand gesture. The band was formed in 1982 after Ronnie James Dio's departure from Black Sabbath, where he had been the lead singer following Ozzy Osbourne's exit. Dio released their debut album, "Holy Diver," in 1983, which quickly became a classic of the heavy metal genre, featuring iconic tracks such as the title song "Holy Diver" and "Rainbow in the Dark." The band's lineup over the years included several notable musicians from the heavy metal community, but centered around Ronnie James Dio's creative direction.
