The tremendous ongoing success of the Vienna Philharmonic Orchestra's New Year's concerts has spilled over into increased exposure for its Sommernachtskonzert or Summer Night Concert, founded in 2004 and given a big boost by sponsorship from Rolex in 2009. The concert is held in open air at Schönbrunn Palace and draws crowds in excess of 100,000; Sony's engineers have coped well with this difficult setting. This kind of program, with a series of short works, on the light side but mixing various registers, would have been familiar to audiences of a century ago, and it remains hugely enjoyable. Pianists Katia and Marielle Labèque enter fully into the fun spirit, with their rendition of Poulenc's Concerto for two pianos in D minor, FP 61, and there are signs that Ravel's Boléro is finally starting to shed its association with Bo Derek's film: it pairs nicely and dreamily here with the Suite No. 2 from Daphnis et Chloé. The program is framed by foot-tapping favorites, with the Wiener Blut of Johann Strauss II as a year-to-year constant finale; Vienna Philharmonic conductor Semyon Bychkov takes just the right tone in these, pushing the tempi for energy but not letting anything get crude. Highly recommended.
