Armored Saint is definitely traditional classic metal as opposed to US power metal. I'm with Sanitarium78 here, if Armored Saint is on this list, Dio should be too. US power metal I'd consider to be like Jag Panzer, Iced Earth, Manowar, Brocas Helm etc.
Also this list is invalid if you don't hit Into Battle by Brocas Helm very, very soon.
Flotsam & Jetsam and/or War Master - 7/9
Grindcore Fest - 7/12
Exodus - 7/25
Impaled (?) - 8/15
Sleep - 8/30
Swans - 9/10
King Diamond - 10/31
