thank you for this video, although I find that the accordion doesn`t lend itself to playing Vivaldi. A composer of genius whom I particularly appreciate, the Four Seasons can only be performed on the violin. Personal opinion, of course, but the finesse of the sound of this instrument (of the devil, as they say) lets you imagine the cold wind, the twirling snow etc...
A brief comparison with two performers, Sarah Chang and Nigel Kennedy.
