Drop A, FUCK YEAH.
I wasn't planning on reviewing, however, you mentioned Drop A, which is what I just recently set my gutiar tuned to.
This all sounds pretty kickass man, however there's a couple things I think you could improve on.
Your drums had a bit too much treble in my opinion. Mind you, that's only my opinion, if you like them like that, then by all means keep them like that.
Your guitar playing is tight, clean (As far as distorted guitar comes), and smooth. I think you could use a little more tone on it. Add a tiny bit of treble to make it stand out more. Once again, just opinions. Not saying that your way is wrong. Just my thoughts.
Anyways, bravo sir. Excellent riffs, excellent playing, superb track.
