Very cool! The rhythm guitars sound like ASS though. I like the overall midrange voicing of them, but they sound really distant and kinda mushy. Your growls sound like you're puking. Not very aggressive. Timing's off in a few places. Clean vocals sound buried and not very confident.
MIDI drums suck, but that's cause they're MIDI. Ever used Drumkit from Hell? It's a pretty easy to use program and the drums sound REAL good.
Pretty good attempt at the song though. I LOVE hearing other people covering Opeth tunes. One of these days I'd like to do a recording of Demon of the Fall. I pretty much have all the parts for it down, just a matter of getting it all to tape.
