What goes on in the shadows of the Jones Theatre, hidden away on the back side of the Denver Performing Arts Complex, shouldn't be kept a secret: The Jones is home to the ongoing theatrical/performance/improv/crazy madness series [email protected] Jones, which produces about four shows each season, some of them ongoing and others a one-shot deal or with a limited run. Yet attending a show here is still a little like being part of a big, wonderful, funny secret, and part of the fun is that Off-Center shows sometimes start or end with a party, with beer and dance music included. Curated by Emily Tarquin and Charlie Miller, the current season of Off-Center has already broken our hearts with Drag Machine and inspired us with the interdisciplinary dance work Audio Kicks; throughout, the returning Cult Following, a live improv show that plays off memorable scenes from the film world, has kept us laughing, with the action continuing on second Thursdays every month through May. Still to come? Sweat: Improv on Bikes, for two days in May. Good thing you still have time to get in shape.
