In performances, Yuja Wang's penchant for short skirts has quickened the pulse of conservative blue-hairs and caused quite the scandal. But regardless of reviewers' woeful assertion that Wang is a classical Lady Gaga, the 24-year-old has a gift for beautifully executing Rachmaninoff, clearly evident with both the dizzying variations of Rhapsody on a Theme of Paganini and the 2nd piano concerto. The dazzling climax of the Paganini is challenging, contemporary and bold -- not unlike the fashion tastes of the performer. Claudio Abbado, not often heard with soloists, conducts.
