in a metal mood

One of the regrets of my youth was that I spent too much money on roleplaying games and not enough on music. Which is to say I spent all my free money on rpgs and none of it on tunes. In particular I rue the fact that I missed the opportunity to hop on the heavy metal bandwagon back when it ruled the world of music. In many ways heavy metal and D&D go together like peas and mashed potatoes. Some people keep them separate on their plate but the awesomest folks mix 'em together with wild abandon.

So I've decided to try to re-edumacate myself on the good ol' days of heavy metal. I'm hoping some of my readers can help steer me to the good stuff. (Paging Dave Hoover. Mr. Hoover please pick up the white courtesy phone.) I'm mostly interested in the period of 1970 to 1983. Why stop at 1983? Because it's got to be hard to avoid irony after the 1984 release of a certain documentary. Below is my tentative list of stuff to look for.

Black Sabbath, Paranoid
Black Sabbath, Heaven and Hell
Judas Priest, British Steel
Judas Priest, Screaming for Vengeance
Iron Maiden, The Number of the Beast
Dio, Holy Diver
KISS (Okay, I can't tell you if these guys are metal or not. But KISS fucking rules.)
Queen (ditto)
Uriah Heep (Are they metal or just hippy freaks with guitars? Do I care either way?)
Hawkwind (see above)
Motorhead
AC/DC
Twisted Sister

So, music scenesters, any other suggestions? I'm looking for the evil and the fantastical. Albums with at least one good chartmaker would be a great place to start.
