DROP G "Epic" Intro Track

I don't know whether it's the kick, the snare, or what, but something is ducking your master buss like a motherfucker.

The guitars are audible, but they're a little muddy.
Not sure also if that's a distorted bass, but that might be why.
 
I think the mix could use some work, but the actual content itself is pretty good. It definitely sounds like you've pushed the compressor/limiter too hard and it's just popping too much. I would aim to get the rhythms and the bass sitting together nicely and give them more room to breath, and then work the drums and everything else into it afterwards.
