I can't say if they are riding retro or just catching up to the rest of Europe, but if you have any familiarity with early Helloween and happen to be looking for more power/speed metal with fast-picked riffs, rapid drums, and accented vocals then you might wanna try Belgian band Fireforce. There's a little American muscle flexed in the guitars to give them a nuance, but this style has been ringed dry unless you really, really want a half dozen more songs about battles and being "born to play metal". Weary, yet stalwartly, they do March On.
