I still can't believe how anybody who listens to metal can say anything bad about Meshuggah. I couldn't understand in any way how someone wouldn't like them, I find them great in almost every way.
Alright then, if you want me to talk about a band that isn't mainstream, here's a black metal band I found some time ago that I think deserves more attention. Tell me what you think, I know I liked them a lot.
