Ha - really is a ride!
Has a nice build to it, from start to finish. Sort of a 'buckle up, bitch, and hang on to something' feel especially when the kick comes at about, like, the half minute mark.
It felt a bit repetitive, but the shift at 1:45 saved it for me. The whole thing feels like it could be about two minutes, or a half more maybe - a little stretched in bits, but the sound are all there and sound mad awesome. :D
