Turns out it's Chris Jericho. No kidding - that dude can sing.
* Massive Digression: A lot of people I went to school with never listened to metal bands - their most vocal fans tended to be the people who gave you the evil eye while you were trying to get books from your locker. They cut class to smoke, huff gas, and listen to Iron Maiden, Slayer, Ministry, Sepultura, Fear Factory, Tool, Prong, Metallica, Megadeth - you name it. That's really not the fault of the bands - it's more a marketing problem the bands have. If you missed out on these bands, then your musical diet is deficient in some important heavy metals. Some of this music is pure adolescent aggression - a lot of it is intelligent, energetic, and powerfully lyrical. Iron Maiden wrote a 12-minute metal version of "Rime of the Ancient Mariner" that was so good that my 78-year-old English teacher had us all listen to it in our poetry class after Beowulf.
