Busoni 's rendition of Bach's chaconne in d minor was very fansatic, so each instrument, violin and piano made this piece intersting to listen to. it's a great piece with much execution of skill and technique on both instruments. The violin is a difficult instrument to learn to play and I do admire how Itzhak Perlman performed this piece. The piano, also requires advance skill and technique as well, to perform this piece. Music has an expression in any instrument along with the skills we acquire in our lifetime.
