hmm. there are MANY too much to tell all of them. some favorites from different genres:
Nirvana, Manson, NiN, Helium Vola, In Extremo, Corvus Corax,
SitD, KiEw, Infected Mushrooms, Think About Mutation, Das Ich,
Tito & Tarantula, Halfort, Blutengel, Feindflug, Funker Vogt, Prodigy, Megaherz.
no special order. but after all, Nirvana is the non plus ultra
