If you haven’t seen The Big Lebowski … well, it’s sort of pointless to try to describe it. On its surface, it’s a satire of the sort of mystery they don’t make anymore, an ink-black noir, driven by a hard-boiled detective in the mold of Philip Marlowe. But also, it’s not that at all. Lebowski is about hanging out with Jeff Bridges’ The Dude, firing up some Creedence Clearwater Revival and smoking a joint behind the bowling alley. It’s a hurricane of madness and nihilism with The Dude at its center, occasionally flummoxed, sure, but zen as a stone Buddha deep down. Sometimes the density of Lebowski’s plot turns off first-time viewers, but across the decades fans have continually returned, not to get to the bottom of some convoluted mystery, but for the vibes. “Cult classic” feels like too quaint a descriptor for the culture that has grown up around this Coen brothers banger since it premiered in 1998. Consider Lebowski Fest, a celebration of the film that has been held in cities across America since 2002, or the Little Lebowski, an iconic New York shop dedicated to Dude-themed art and memorabilia. The shop tragically closed in 2015, but the spirit of Lebowski fandom lives on. This April, Pearl Street Warehouse is hosting the fourth annual Big Lebowski Experience, in which D.C. musicians will take on the personas of characters from the film, including The Dude, Walter, and Maude, and perform music from the soundtrack. Expect to hear covers of songs by Creedence, Dylan, and Elvis Costello, but not the fuckin’ Eagles. (Just kidding—Eagles too. Sorry, Dude.) The Big Lebowski Experience IV starts at 8 p.m. on April 21 at Pearl Street Warehouse. pearlstreetwarehouse.com. $15.
