Edguy, Holy Grail, Cauldron, all very similar to like old school metal in the 70s and early 80s I'd say.
It's not fast, but Orchid is a pretty awesome band that have a black sabbath vibe. I suggest their song Eastern Woman.
The Sword are great, but their songs are about nerdy stuff like vikings and magic and what not and their singer isn't the best. But it's not screaming
If you're okay with like "power metal" as people call it (has some opera/symphony kind of influences but still super metal), there's a band called Dragonland that are WAYYYYYYYY better than their name suggests.
Other than that, i dunno. I'm more of a death metal guy.
