Ooooo...so jazzy! :D This piece really displays your excellent sense of rhythm. I love the variety - sometimes it's emotional and light, at other times it's dark, energetic and heavy. I'm usually a fan of using clashing chords to channel emotion, but I think you almost went a little too far this time. Improvised jazz can seem random if not carefully structured. That said, there was a good sense of direction throughout the piece. I thought it was all pretty smooth-flowing, and I especially love the transition into 4:45. Very groovy around that part. It then quickly evolves into a lighter, emotional piece around 5:10, though - I love all the ups and downs! I also really liked the part at 6:50. There's no doubt that you're incredibly skilled at playing the piano. I would suggest that you try this improv again with some of the same themes/ideas, now that you've had an initial chance to flesh them out. I understand that you used only a few chords throughout, and it's all in the same key, but to the casual listener it comes off as a little arbitrary at times. Oh, and I know the recording got cut off while you were playing, but please at least reverb your way out next time (yes, I just used "reverb" as a verb). Electronic manipulation would do you some good at the end of this piece in order to properly wrap it up. Sorry I'm being so critical. Overall, I was very impressed, of course. Keep up the great work! I love your piano improvs, LSD! :D
