As per the thread:
https://www.pianostreet.com/smf/index.php/topic,15090.0.htmlHere is one of my old improv's. It was done on my old Kawai upright. I removed both the top and bottom front pannels of the piano to get much more sound from the tiny piano.
Mic: IBM Thinkpad 380XD built in mic
Piano: Kawai CX-5 upright
Enjoy!
