In the Further Proof That Cancer Is Fucking Evil department, heavy metal great Ronny James Dio succumbed to his battle with stomach cancer this morning at age 67. If you grew up as a metalhead in the '80s, or if you just appreciated peerless powerhouse vocals, you were a fan of Dio's. Whether in Rainbow, during his stint as Black Sabbath's frontman after Ozzy Osbourne's departure, or in his solo career, RJD was one of the all-time greats. Besides the strength of his operatic vocals, I love Dio because he was from that now long-gone era of metal where even if the imagery of the lyrics and the LP art veered into the cartoonish, it was never played as a joke. When Dio flashed the devil sign, or prowled through a video in a sword and sorcery get-up, it wasn't meant as a post-modern goof, it was all 100% sincere. Hard to believe that a voice so powerful is no more.
