Ok my turn now, you guys listen to many stuff i've never heard, and we'll allways have diferrent opinions, but from a portuguese point of view:
Pantera - you can't stop loving A Vulgar Display of Power, that's all that is and much more
Metallica - What???? until black album, that's the best there is, ok my fav is master but they ruled the earth with black
Sepultura - Brute Brasilian POWER Agressive music for the masses
Ratos do porão - Another brasilian punk/metal band that no one talks about, try listening to just another crime in massacre land
Machine head - Great first album
Tool -fabulous in every way
Isis - Strange experience
MASTODON - The best 2009 album, the band that brought metal to life again, extreme
Slayer - Altough it's not one of my fav's great power band, real aggressive.....
I could go on forever
And what makes a metal band??????
Surelly not those little techique guitar players with tight shorts and crasy makeup hair but the feeling, the agression, the power that they thrive into the music, Dream Theater and such as them, baHHHHHH, ok they play like crazy but........they are just little wusses........
Welll.........
