There are times when Dio-fronted Black Sabbath totally trumps the Ozzy-era stuff. ("Neon Knights", "The Mob Rules". I could go on.)
But nothing ever blew my BMX/burnout/80s metalhead mind like being shown that the DIO logo (above), when gazed upon upside down (below), reveals the word: "Devil". This was brought to my attention, like most valuable things in the 1980s, by someone's older brother. 25 years later, I demonstrated the same visual trick for Irwin Chusid, and it blew his mind, too.
Also, re-watching the video for "The Last in Line" suggests that the song is, in fact, about an Italian-American kid who goes to hell through a portal in a suburban office park, and is forced to play loud video games.
Now that's rock & roll. Rest in peace, Ronnie James Dio.
