Three artists. Three eras. One genre, built album by album.

Sabbath. Birmingham, 1970. Tony Iommi playing detuned guitar through prosthetic fingertips. Geezer Butler writing about war, the devil, and his own racing mind. Bill Ward swinging behind the kit. And out front, a young Ozzy Osbourne wailing the words to “Iron Man,” “War Pigs,” “Paranoid,” and “N.I.B.” Eight albums later, heavy metal had its blueprint.

Dio. When Sabbath replaced Ozzy in 1980, they hired Ronnie James Dio, and the songs got bigger. “Heaven and Hell,” “Neon Knights,” “Mob Rules” — and later “Holy Diver” and “Rainbow in the Dark” with his own band. Dio brought operatic thunder and fantasy imagery to heavy metal. He gave the genre its mythology, and the devil horns its proper salute.

Ozzy. Meanwhile, the Madman started over. “Crazy Train,” “Mr. Crowley,” “Mama, I’m Coming Home,” “No More Tears” — four decades of Ozzy solo records turned the Prince of Darkness into pop culture itself. He played his last note at the “Back to the Beginning” reunion in Birmingham, July 2025. Weeks later, he was gone. The songs aren’t.

DiOzzy plays all of it. The Iommi-fueled doom of early Sabbath. The operatic thunder of Dio. The unhinged catalog of the Prince of Darkness. Three voices, one bill, every riff that mattered.

Turn it up. Throw the horns. Welcome to DiOzzy.
