The Nevada Conservatory Theater has staged a shocking old play in its experimental season at the Black Box Theatre. "Spring's Awakening" was first performed under heavy censorship in Germany in 1906. It closed after only one night in New York 1917 amid public outrage and charges of obscenity. The story traces the dawning sexual awareness of four teenagers who, in their painfully funny contradictions, are at once too innocent and not remotely innocent at all. Definitely rated R.
