Dear Xavier, I'm suffering from some health issues (almost there!!!) which prevented me from recording a lot of videos. I still give some lessons now and then. Maybe we can do a Zoom/Skype session to talk about what you want to learn or wht fascinates you. This is just an informative call and free of charge, no lesson. christofchapsis@gmail.com Cheers and thanks for the compliment! Christof
