E Nomine (One of my favorite bands, in general - they are my favorite, obviously, on this top three list)
Tangerine Dream
Rammstein

rammstein

Ansoticca - Willing to Believe - YouTube

Kreator, all the way

Katharsis, easily.

I've only recently discovered Rammstein and I know they're one of the most command bands to like but something about their sound does appeal. It feels powerful but not too heavy.

RAMMSTEIN. Oomph had one song that I really liked called, "Augen Auf", but Rammstein had like 20.

I love Kreator.
But Hanzel Und Gretyl is the ****.
Didn't care for their latest LP but their older stuff is bad ass.

They are kind of like Rammstien except they are really fukken good! And way heavier!

There should be a German band named Duetche!

Kraftwerk

and also Spermbirds (even they only have one good record).
