Builds man, builds
Okay, so at :30 to :50, it was great. The bass had really kicked in, and around 1:04, that was great too.
But then, it didn't build past that. I mean, a couple of short breaks at 1:36 and at 2:24 you have kickass snares (can't think of the appropriate term at the moment, that's the closest I can think of) rocket in-
And then it's back to the same line that we heard right at the beginning. The energy stays the exact same. You could have punched up the tempo or the volume easily, but it stays flat. Where's the anger? The kickass bass that starts at :30?
Don't get me wrong, it has the makings of an epic song, but it really isn't more than a 6/10 for epicness. Seriously, why wasn't there a massive punch right at 2:43? Without lower lows and higher highs, the strongest moments in your music don't look any different than the weakest.
Trance is a good genre for looking at builds as it encourages builds. Paradoxial March By Gravey might also be a piece worth looking at- he has epic covered.
