This is some heavy stuff.
The kick drum is awesome! The overall sequencing in this track flows greatly. The leads are heavy as hell. I know what you are talking about with the side-chaining thing, works just fine.
- The lead is almost being killed by the bass drum. Try raising the high frequencies on the EQ or something, it's not really that big of a deal anyway you can leave it and it still would sound great.
It's a banging tune overall. I hope to hear more of this work. 5/5
