San Francisco Opera's world premiere of "Girls of the Golden West," set during the 1850s California Gold Rush, was created by the renowned team: composer John Adams and director/librettist Peter Sellars. Sellars and San Francisco Opera general director Matthew Shilvock will discuss the production and its mix of wildness, optimism, greed, violence, humor and racial prejudices in the stories of three Gold Rush women whose lives intersected in a small mining community in the Sierra Nevada mountains in 1850. "Girls of the Golden West" is based on factual events and persons.
