England for sure there are some, the notables, Priest and Maiden, the U.S doesn't have many that are still stellar as used to be, Dream Theater, Kamelot, maybe Queensryche, Megadeth.
Germany though has some good bands, have you forgotten one of the thrash legends, Kreator, legends who are still doing well today, Blind Guardian another excellent band that seems to be getting bigger year after year, let's not forget Edguy either another very talented band, there are some more but those are some of the bigger ones that thought would mention.
