If I may say so, the first 40 seconds of this second are absolutely bomb-ass. I don't know what it is, but it all just sounds so... perfect. That isn't to say that the entire piece isn't great, though. I don't really mind the guitar change at 1:33 - it adds some nice variety, I think.
I gotta agree with the guy up top, but I'm pretty sure he's talking about 1:24 and not 1:42. It sort of builds up to something and then just fades away. Other than that, this song is pretty awesome. Can't wait to hear the entire thing.
