...Aaaand I got carried away. >_< Sorry if those are too obvious and you already know 'em (I left out super-obvious stuff like Priest/Maiden/Sabbath etc. because of that). I can adjust with more obscure stuff if you like.
Is power/thrash or power/heavy okay? If so, I'll add...
Metal Church - Metal Church
Running Wild - Pile of Skulls
Jag Panzer - Thane to the Throne
Ok, I'll stop now.
