[Mad Melvin]

Helm listed some excellent albums and im sure youll find something you like from there. However I would like to add a few bands to that list:

Dark Tranquillty - Damage done
Great album imo. I havent heard any other stuff from them, but I´ve heard that their other albums are good too.

Edge Of Sanity - Crimson II
A friend of mine suggested this album to me and I must say its excellent.

Children Of Bodom
All of their albums are great.

Strapping Young Lad - SYL
This was already suggested by Helm, but this band is so good it deserves to mentioned a second time. I higly recommend this album. Gene Hoglan is a fucking god.

Hypocrisy - Catch 22
Fantastic. Catchy songs.
