That was one quite interesting discussion. Now, time to listen to the track.
EDIT:
I'll comment as I listen.
"Infernal": Quite like the sounds of the intro. Seems to build up in tension now as it's passed one minute. It's getting more intense, nice development. I don't know if the 'bad sound' replies were mounted on this one? I thought it was, so I was a little surprised by the nice sound in this one. I'm afraid I got no complaints about this one.
Now "Sigma pt3": A little similar, just faster intro. Very refreshing. This is not the kind of music I have been making, so it's very interesting. I'm afraid I've still got no complaints about the sound. I really liked both tracks.
HOWEVER; based on the previous posts, it seems like you should open up a bit more and realize that not everyone has the same approach. I know this myself, as I've been playing guitar for a while, and reading music thoery, but since I started doing "hour compos" I've ended up last several times and got quite some amounts of critisizm for my composition; ESPECIALLY sound-wise. What I know about playing technique/music theory, I lack of sound/editiing knowledge. Just a reminder. In case I happen to dislike something in your next track =)
