Two of the rock stars of the classical-music world, Lang Lang and Gustavo Dudamel -- both known for their expressiveness and charismatic stage presence -- are set to jam with the LA Philharmonic at the world-famous Hollywood Bowl, on a pair of suitably dramatic works by passionate Russian composers. Performing since the age of 5, famed Chinese pianist Lang Lang has played for presidents, queens and prime ministers and with almost every major orchestra on the planet. He's also released more than a dozen acclaimed albums and is a Grammy favorite, with heralded performances alongside Pharrell, Metallica and Herbie Hancock. He'll join artistic and musical director Dudamel and the LA Phil for Tchaikovsky's instantly recognizable Piano Concerto No. 1 and Rimsky-Korsakov's equally well-known Scheherazade.
