"Hanging Georgia," a new play about the fiery relationship between painter Georgia O'Keeffe and photographer Alfred Stieglitz, roils and explodes across the stage like a Texas lightning storm.

Sharmon J. Hillfinger's play -- getting its world premiere by Oakland's TheatreFirst and the BootStrap Theater Foundation of San Francisco -- blends dialogue, music (by Joan McMillen) and stylized movement to tell the story of the two artists who, in their own ways, helped define mid-20th century art.
