Okay, I just registered to OCReMix, after having listened to remixes old and new on this site for a year and a half or so.
I'm a pianist, a video game pianist at that, and this remix still blows me away every time I listen, which is pretty damn often for a song. It has inspired me just to learn the note patterns of this remix (by ear) and just improvise and go crazy like Spekkosaurus does here. every second of this piece is just so fucking cool, well-played and almost hair-raising
This OCReMix is godly as far as solo piano goes on this site, and it must be listened by everyone, like djpretzel says highly recommended.
