Since The Nutcracker's first production in St. Petersburg more than a century ago, its charming story, dazzling choreography and magnificent Tchaikovsky score have combined to make it one of the most popular and enduring ballets the world over. With its setting transposed to San Francisco's 1915 Pan-Pacific Exposition, SFB artistic director Helgi Tomasson's production features sets by Michael Yeargan and costumes by Martin Pakledinaz.
