I don't know how I just found this thread. I'm a huge metalhead and have been for about 25 years. I started with Metallica, Pantera, Anthrax, medageth, and slayer. Then I discovered newer metal from around the world and fell head first into it and never looked back. Most of the bands I like no one will have heard of. They don't get played on the radio or anything.
Bands like:
Soilwork
Circles
Twelve Foot Ninja
Meshuggah
