Hey !For the recording: I have a silent piano, meaning it's acoustic but I can play with headphones too.I used headphones, and I pluged the second headphones output directly on the mic input of my computer and recorded it using the software Audacity.So the sound you hear is synthetic ( but nicer than my out-of-tune piano anyway ). Note that the piano is 14 years old and that Yamaha did an awesome work with the sound at the time !I took the video separately with a camera and then put everything together on my computer.And yes there are two cuts, actually I mixed 2 recordings because I was not happy with some parts of each (but don't tell anyone, will you ? ).
Wow, Gershwin spirit is really there. I think I have the sheet music of this, it sounds pretty similar, played it a few times but found it pretty difficult, you inspired me to have a look at it again.The book I have has about 8 improvisations of gershwin.
