The event takes place 6-9 p.m. on Feb. 23 — the 25th anniversary of the last day in the life of Laura Palmer, whose mysterious murder was the cornerstone of the television show.
"We just wanted to do something fun. Many people are fans of Twin Peaks, and it seemed like the anniversary should be observed in some way," said Paul Durica, who founded the walking tour and re-enactment group in 2008.
Held at Maria's Community Bar, the event will feature a trivia contest, "Miss Twin Peaks" costume contest, a screening of the pilot episode and a spinning of the show's highly touted soundtracks.
"For the condemned characters of Twin Peaks," wrote Guardian culture writer Ben Beaumont-Thomas, "the music is not merely a decorative hood, it's the scaffold from which they're hanged."
With its supernatural weirdness, the critically acclaimed series developed a cult following that still draws fans to dress as characters at events like comics conventions. The show had a two-year run on ABC in the early 1990s, plus a prequel film.
The benefit party is part of the monthly "community night" series at Maria's, where some of the proceeds from drink sales will be sent to local groups.
Pocket Guide to Hell is known for its guerilla walking tours and historical re-enactment of city crime and events in Chicago's explosive labor history.
Durica said the proceeds will go toward costumes, props and performer honorariums for future productions, including the "Destination Freedom" radio show and re-enactments of the Camp Douglas POW camp and the Pullman strike.
"These programs cost money to produce, but we want them to remain free and accessible to all Chicagoans, which is why we have periodic fundraisers like the Twin Peaks party at Maria's," Durica said.
