Kennedy and his Polish Orchestra make Vivaldi alive indeed. Lots of passion and interaction, with both the orchestra and the audience. However, Kennedy can be amazingly sensitive and singing in the adagio meditations in the Four Seasons. The Purple Haze encore is lots of fun as well. BEautifully done! Clearly filmed -- the players are showcased as well, although I would have liked more of the cellos!
