The Squire Strokes Back Vol. 3

Monday, August 21, 11 p.m.

The Squire Lounge

Roaring back to life like a passed-out drunkard at last call, comedy returns to the Squire Lounge in gloriously destructive fashion on Monday, August 21. While the weekly open mic may have gone the way of the black rhino, local comics and fans alike hold fond memories of the bygone Denver institution. Luckily for these scumbag nostalgists, Squire Strokes Back producer and comedy super-fan Chris Baker has enlisted Greg Baumhauer to host a new late-night standup showcase during which he'll roast the crowd and his fellow performers alike. Monday's show features local jokesmith Jodee Champion along with a cavalcade of visiting comics in town for the High Plains Comedy Festival, including Pittsburgh's Shannon Norman, Chicago's Danny Maupin, Las Vegas's Brandt Tobler and New York City's Owen Straw, Shane Torres and Jono Zalay.

Sunset Cinema Presents: Step Up

Tuesday, August 22, 6 p.m.

The Galleria at the Denver Performing Arts Complex

From Singin' in the Rain to You Got Served, dance sequences provide some of the most purely joyful movie moments in cinema history. The Denver Performing Arts Complex's month-long Sunset Cinema series, which concludes on Tuesday, August 22, celebrates the art of dance on film with free screenings of fleet-footed classics. Although 2004's Step Up may not offer much in the way of story, its expertly choreographed moves and sugary escapism launched a five-film franchise, turned the agile Channing Tatum into a full-blown movie star, and inspired a rash of lesser imitators throughout the aughts.

The Doom Room: High Plains Kickoff Show

Wednesday, August 23, 8 p.m.

Ratio Beerworks

Ratio Comedy staple the Doom Room calls upon comedians to be funny without the safety net of their joke books, while they riff on a random assortment of topics that pop up on the nearby screen of doom, all while being heckled by the Darth Vader-esque voice of doom (Nick Gossert of Lucha Libre & Laughs). It's a steep challenge, and some of the performers ride a wave of laughter from the beery crowd while others crumble by the second prompt. For a performer, the show is a nerve-racking trial by fire, but for audiences who love a healthy dollop of schadenfreude with their jokes, there's no better show in town. The showcase on Wednesday, August 23, is an official kickoff show for the High Plains Comedy fest, with a lineup that features local Doom Room champions Patrick Scott, Georgia Rae, Cory Rhoads and Katie Bowman, along with prodigal Denver comics Jordan Doll and Chris Charpentier, with headliner Shane Torres (who's put together quite a run of shows during his visit to town). Join hosts Andrew Bueno and Ian Douglas Terry for a flop-sweat-riddled giggle fest, and enjoy a free taste of High Plains to whet your appetite for the gauntlet of funny that awaits.

Thursday, August 24, 6:30 p.m.

Levitt Pavilion

FirstBank’s Latin Concert Series at Levitt Pavilion continues at 6:30 p.m. Thursday, August 24, with a live performance from the talented Gaby Moreno.

Luckily for thrifty music fans, FirstBank — in partnership with local pop radio station 95.7 The Party — is presenting the concert, which also includes opening act Vanessa Zamora, for free. The new Levitt Pavilion is at 1380 West Florida Avenue; RSVP and get more information at levittdenver.org.
