Hi Matt,
Yeah, the song builds well, right through the track.
I see you're a drummer... They come across really well, although I'm no expert on mic'ing and mixing real drums. I have had experience in that area, and I used a simple arrangement of a stereo overhead pair of condenser mics, a SM58B on the snare and an AKG dedicated kick drum mic (can't remember which model). I'm guessing your setup is a bit more comprehensive than that...
Nice track by the way... Might even be EPIC
cheers
andy
