Sausalito, CA's Antenna Theatre has a hit on its hands with Pandemonium, an environmental-theatre production that takes audiences into the woods -- literally.

Created by artistic director Chris Hardman and directed by Tori Truss, the production, which guides audiences from scene to scene in the woods and meadows adjacent to the Headlands Center for the Arts in Marin County.

The production has extended its run, adding performances are June 28 and 29 and July 12, 13, 19 and 20.

Exploring the rites of spring, marriage, family and suburbia in the woods and meadows of the Marin County headlands, Pandemonium "is about sex basically," said Hardman.

Audience members wear radio headsets and listen to pre-recorded material, "we walk them into the forest [and] tell them our tale of hormonally driven young people," said Hardman. An ensemble of masked dancers and mimes are joined by bunraku puppets, who play the two main characters. Hardman describes the piece as "not theatre in the traditional sense...it's theatre in real space," Pandemonium is an "outdoor adventure without the laws of theatrical control."

Pandemonium is the second in a series of walk through-plays by Hardman, following the seasons of the year. The next, focusing on Winter, is expected in November or December. With this style of theatre Hardman hopes "to make shows become events, to go from the linear, dramatic form to something more participatory."

The show begins at sundown. Audience members meet in the parking lot of the Headlands Center for the Arts, 944 Fort Barry, at 8:30 PM. Advanced reservations may be made by calling (415) 331-8512. Tickets cost $12-$15.
