Peter Eötvös’s The Golden Dragon, “based on a play by Roland Schimmelpfennig [and set in a Chinese restaurant], has a cast of five who perform multiple roles that include ‘Chinese mother’, ‘Chinese aunt’, ‘Old Asian’ and ‘An Asian’.” Music Theatre Wales, generally a respected touring company admired for its unconventional productions, has fielded an all-white cast for the piece and is drawing criticism for it.
