The UC Davis production of Oklahoma! is a glossy eye popper—much fancier than a community production, though not as deep vocally as a Music Circus show. The cast includes two professionals, plus undergrads, with capacity crowds opening weekend. F, Sa 8pm, Su 2pm. Through 5/10. $12-$28. Jackson Hall at Mondavi Center, UC Davis; (530) 754-2878; www.mondaviarts.org.
