Katie Derham introduces this year's traditional spectacular concert from the Vienna Philharmonic Orchestra in the gardens of Schonbrunn Palace. There's a distinctly French flavour to the evening with music from Bizet, Berlioz, Poulenc and Ravel, and a special appearance from the world-renowned French piano duo the Labeque sisters. The concert is conducted for the first time by Semyon Bychkov who, though Russian-born, is an honorary Frenchman on account of his being married to Marielle Labeque.This year's concert features such musical favourites as Ravel's exuberant Bolero and his ravishing Daphnis and Chloe. There is also a chance to dance along to the can-can from Offenbach's Orpheus in the Underworld plus, of course, the traditional end to the concert, Johann Strauss Junior's romantic waltz Wiener Blut. It wouldn't be a summer's night in Vienna without it!
