The millennium approached, then quickly fell behind us. Time marches on, but Tony Kushner's Angels in America remains a landmark achievement of 20th century theater.

The legacy of the play that got its start at San Francisco's Eureka Theatre is on display at the Museum of Performance and Design, one of San Francisco's best kept museum secrets. The exhibit hall may be filled with memorabilia from Angels' humble beginnings on a red Formica table filled with scribbled-in notebooks to its domination of world stage (with the Pulitzer Prize and international posters to prove it), but what you really feel in this display is the extraordinary power of theater.

It doesn't happen very often, but when a play or a musical really taps into the American psyche, imaginations are ignited and artists are pushed to do work they didn't know they could do. MPD's curator of exhibitions and programs, Brad Rosenstein, has created a testament to the evanescence of theater. Plays may come and go, but sometimes in their wake, the world changes.
