for people who like awesome, really heavy music from good ol' germany, i have two tips:
1st: pavor - from bonn; they play an extremely heavy progressive metal with a bassist you've never heard before

hock:- he plays his 6-string bass with amazing speed & skill (without the band it would be free jazz :wink: )
the rest of the band is also ...hmm, let's say KICK ASS!!!
http://www.pavor.de/2nd: Disillusion: - from halle; in my poinion even more amazing than pavor. the music sounds like ...how dream theater should sound like. it has all the good elements without the flaws. awesome! they manage to compose songs of over 15mins without getting boring or anything with extreme technique-skills.
