Accept. Been a fan since Restless And Wild.Didn`t think they`d be the same after Udo left but the last two albums( Blood of Nations & Stalingrad) have been very impressive.
Accept (especially with the last two albums).
Darkseed.
Tiamat.
LucyFire (the Tiamat singers side project).
Crematory.
U.D.O.
Running Wild.
Helloween.
Grave Digger.
To name a few. There are more but the names escape me for now.
