So at 2am yesterday night, I decided to play on my (electric) piano, since I have touched that thing for almost a year when I had to cease piano lessons due to school. After being at it for a few minutes, I realized that I was in a good mood to do some improvisations, and played for 20 minutes! I've recorded it as well, so here it is. Please pardon my complete lack of harmony and rhythm through the piece -- I am just trying to come up with random things that sound good at the spur of the moment. Good luck making it through the 20 minutes without falling asleep!
