Great stuff Beepster!
I got nothing to add to the comments on the mix. Sounds like TH2 performs well in this tune! I am just curious, do you have all your drums coming in on a stereo track and mess with the entire kit there? Or are you sending all your drums to individual tracks in Sonar for a full detailed mix?
Anyway, here's just a small tip; when you've mastered mixing the drum kit, you should start looking at the velocity lanes in the MIDI track, especially for the hihat and ride. When they are hammered on at 127 all the way you get the machine gun effect which is destroying the authentic sound and also, it sounds not as good;) Small adjustments all the way to the velocity of the MIDI notes remedies this really, really well. Actually, I use Sonar's Velocity MIDI plugin for this a whole lot. And Groove Quantizing to mess up the timing just enough to have it sound more human. Look into it some time, you'll love it!
So, the song it self, that is what matters, it's great! It's one bad ass metal tune and can't wait to hear you making stuff with vocals. However, the guitars speak nicely for themselves in this one and the shredding is, as the last time, right on the spot!
Well done!
