The city has the Capital Fringe Festival, with its mix of one-man shows, oddballs and physical theater, and the e(merge) art fair, effectively a showcase for performance art. But this week will be the first major showcase of audience-driven, unscripted theater. The inaugural District Improv Festival, opening Tuesday, brings in troupes from the District, Baltimore, New York and as far away as Toronto and Austin, Texas, for six straight nights of fly-by-the-seat-of-your-pants theater.

The festival, which takes place at 14th Street theater hub Source, will showcase long-form improv. Think "Whose Line Is It Anyway?" with more of a character arc, says Dan Miller, one of the festival's board members. Every show will begin with a suggestion from the audience. "Everything from there," says Miller, "is unscripted and spontaneous." If you're curious, you have a chance to check out the festival without buying a ticket; admission to the opening night show, starting at 8:30 p.m. and featuring a handful of local troupes, is free.

After Tuesday night's free show, tickets for the festival's performances are $15 apiece; a festival pass is $40. The full schedule is below:
