The yankee power metal is different than the euro stuff, it's tastefully mixed with thrash metal and the cheesier side is stuff like Manowar and Virgin Steele.
On that note I can't listen to Helloween without wanting to vomit, listened to some a while ago and had to bail after hearing the song "Future World".
Here's a great classic of the genre, funny how the vocalist sounds like Bruce Dickinson. There's a one grating song though, but the guitar work is marvelous.
Some decent stoner metal, sounds tr00 enough.
