Oomph! most definitely. Great band, unique sound despite all the music on the market these days. And of course the one German band everyone knows, Rammstein, best two NDH bands in Germany. Paul van Dyk, though not a band, does some of the best dance/trance and remixes I have ever heard.

On the topic of Finnish bands, Kotiteollisuus is a great metal band. And Poets of the Fall are also very good, albeit not a metal band.

Tschüß!
