I must say - I do enjoy your videos Wiwi...Keep them up - it's good to see people recording the 2-part pieces and synching them together - takes a lot of skill on your part, but you're doing them well. Well done. PS - Interesting question - was that an octave glissando I saw you doing in the 3rd Movement Cadenza??? It looked like it, because if it wasn't, you wouldn't have used your thumb for it (going up)...It looked that way, although I didn't think RH Octave glissandos going up existed... I thought they were always coming down.
sh*t - that's gotta hurt the pinkie finger... surely???
