Founder Fights, May 20

Ever had the urge to punch your boss? You might not be alone—but now you can take a swing for a good cause. As a part of Boulder Startup Week, the first-ever Founder Fights will invite top company founders—entrepreneurs, venture capitalists and creatives, all of whom have trained with Corner Boxing Club co-founder Carrie Barry—to go glove-to-glove in the ring to raise funds for their charities of choice. Fri 7-10 p.m. Boulder House, 1109 Walnut St., Boulder. Ticket prices vary.

Project Pabst, May 20 to May 21

An all-American block party in RiNo wouldn’t be complete without a great American beer—and this ale-infused music festival has plenty of cans and jams to go around. Crack open a high-energy Friday night of music at various Denver venues: See the Giraffes at Lost Lake; toe-tap to Doom Tree at the Marquis Theater; and hold your beer upright for Built To Spill at Summit Music Hall. On Saturday, festival-goers will don sunscreen and a pair of shades for the day-long block party on Larimer Street, featuring the Violent Femmes, Nathaniel Rateliff & the Night Sweats, Big K.R.I.T., and more. Fri-Sat, times vary. 2700 Block of Larimer Street. $65.

Colorado Dragon Film Festival, May 20 to May 22

The famous Colorado Dragon Boat Festival has expanded to the silver screen. This celebration of Asian-American and Pacific-Islander heritage features everything from comedies (Awesome Asian Bad Guys) and documentaries (Changing Season: On The Masumoto Family Farm) to anime flicks (Wolf Children). Spring for the opening night VIP reception to meet the director of Uzumasa Limelight, a Charlie Chaplin–inspired film that follows a “kirareyaku,” or an actor whose sole role is to die in Samurai films. King Center, 855 Lawrence St., 303-953-7277. $6-$30.

Hops of Hope, May 21

Fund-raisers are as common as craft breweries in the Mile High City, but when you put the two together and add a blind taste test, your night becomes more interesting. During this charitable evening, you’ll sample pours from Diebolt Brewing, Lowdown Brewery, Mockery Brewing, and Zephyr Brewing Company—without knowing which company brewed which beer. Folks can also fill up with treats from Little Man Ice Cream, Gusto’s Kitchen, and Mile High Cajun. Proceeds benefit Children’s Future International’s Fun Season program, which provides enrichment and leadership activities for students in Cambodia during their summer breaks. Sat 2-10 p.m. Posner Center for International Development, 1031 33rd St., 720-382-7631. $10.

Dumpster Dinner, May 21

One in eight Colorado households is food insecure, yet Americans throw out $165 billion worth of food each year. To combat this problem, Denver organization We Don’t Waste rescues unused foodstuffs that would otherwise end up in a landfill—and now the nonprofit is entreating local chefs to help them transform their finds. Cooks like Mijo’s John Depierro and Daniel Asher of Root Down and Linger will create your recycled meal while local distilleries and breweries (think: Laws Whiskey House and Declaration Brewing Company) provide libations, and rock group Rob Drabkin plays live. Stick around for more excitement at the Dumpster Dance, which will feature acrobatic bartenders and a butchering demonstration. Sat 5 p.m. Studios at Overland Crossing, 2205 S. Delaware St., 303-282-0573. Ticket prices vary.
