This is me playing the cello. I used to do it professionally. Last week (Feb 2018) I took it off the case for no reason and started to play as well as for no reason I'd put it there thirteen years ago (when I got married) and let it there abandoned along all this years.
I'll record the other dances on some rainy day. :-)
(Recorded with my laptop web cam and microphone, only option at hand, so the video and sound are low quality.)
By the way, if you need a cellist in Barcelona or surroundings contact me.
