Superb. Incredible range of tone color. Very intense. Good jazz feel. What kind of piano was this, it doesn't sound like a Steinway (I could be wrong). Bosendorfer, Bechstein? Other?
The opening is certainly an interesting interpretation and good since an improvisation was a requirement in this case. I couldn't get away from the feeling that it overall sounded too legato, probably the recording, the bathroom effect as pianistimo pointed out The softer touches are quite ineffective in the recording the dying away at the end highlights this. Certain parts you want to just bite you but it smooths out. Some wrong notes but that is to be expected for a tough piece like this but entertaining stuff nonetheless! Not many people can pull it off.
