Go listent to Bury your dead and Horse the band. GRIND CORE FOR THE WIN.
I'll ignore the fact that neither of those bands is remotely grindcore, but I strongly feel the need to comment on this. I'll start with a story:
Once upon I time I went to see a Dragonforce concert. The first opening band sucked so I mulled around the venue a bit. Then I went back to see this band called "horse the band" play, as I had never heard of them. The guys got up on stage and didn't look like an emocore band so I stuck around as they proceeded to play. I soon gouged my ears out. The end.
Horse the band is the single worst band that I have ever had the displeasure of sitting through live, and living in massachusetts, I have sat through hundreds of shitty *-core bands. The musicianship sucks, the songwriting sucks, their stage presence is terrible, and the vocalist rambles on about nothing like a douchebag. If anyone was actually going to take his advice and even think of looking for their music to download I strongly advise agaist it. Your ears will thank me!
On topic:
I downloaded a tristania CD once a long time ago, it was ok for what it is, but not really kind of music. The chick is pretty hot though.
