Stickerbrush Symphony (I think that's the actual name of the Bramble Theme) is probably the first piece of videogame music that ever stood out to me as being truly outstanding. I remember when I was really bored with DKC2 (Couldn't get past one of those blasted rollecoaster levels), and just messing around, and I came upon the sound test. When I listened to this track, I was shocked at how rich and powerful it was. It began with an airy, floating feeling, with just a hint of solemness. I can barely describe it. Then, after the first rendition of the main melody, the percussion kicks in. Almost like taking a nap in the treetops of the Amazon... resting in the gentle warmth, bathing in the flourescent green of the sun, shining through the leaves. And then, when that percussion started, it was like you woke up and said "What the Hell. Dude, I'm in the jungle!"
As beautiful as that piece was, this one kicks the everlasting piss out of it. It takes the feel of the first one and magnifies it tremendously, through use of better instruments, more depth, and hipper percussion. This, and Scott Peeple's "Another Inspiration" are easily the two most amazing mixes on the site. I downloaded them over a year ago, and still listen regularly. If I'm stressed out, no matter what I'm stressed about, this mix takes me away from my complex life, and puts me back in those treetops. Such is the power of a good musical piece.
Protricity, you are awesome.
