David Liebe Hart at Beauty Bar

In his own words: “David Liebe Hart is an actor, musician, painter and alien abductee.” Aw, he’s being too modest. Hart is also a puppeteer, podcaster, street performer, an occasional featured star of Adult Swim’s Tim and Eric Awesome Show, Great Job! (a show whose rabidly enthusiastic four-quadrant appeal I will never understand, but nevertheless respect) and the closest thing we have to a gene-spliced clone of Wesley Willis, Daniel Johnston and Fred Rogers. In fact, let’s just get this out of the way right now: It’s a near-certainty that this show will be atonal, uncomfortable and the weirdest thing that’s happened on Fremont Street in at least a month.

But what rewards await the brave, the curious and anyone who wants to make sure they’re never asked on a second date? Like Willis, Hart switches back and forth between keyboard-driven hyperactivity; like Johnston, he has an earnestness that keeps his outsider sounds from tipping into parody; and like Mister Rogers, he’s the main occupant of his own neighborhood. With Time Crashers, Sheiks of Neptune. September 20, 8 p.m., $10. –Geoff Carter

Cannabition Cannabis Museum Grand Opening

Featuring a 24-foot glass bong and the 1973 Chevy Caprice from Fear and Loathing in Las Vegas, the Cannabation Cannabis Museum is ready to teach Las Vegas about marijuana’s past and future. “We see this as a coming-out of sorts for the social side of recreational cannabis,” says Cannabition founder JJ Walker. September 20, $24, 450 Fremont St. #140. –Chris Kudialis

Moving Sale at Zia Record Exchange

The Sahara store will soon give way to a larger west-side location on Rainbow, so you get buy-3-get-1-free deals on the entire used inventory (plus double points!) to help Zia lighten its load. 4503 W. Sahara Ave., 702-233-4942. –Spencer Patterson

Patton Oswalt at Ka Theater

It’s tempting to call Patton Oswalt “one of the best comics working today,” but it also underrates him. After eight hilarious albums, dozens of strong acting turns (in movies like Ratatouille and TV shows like AP Bio) and several years authoring America’s best Twitter feed, Oswalt has earned “of all time” standing. September 22, 9 p.m., $50-$80, MGM Grand. –Geoff Carter

Cirque Mechanics: 42 Ft at UNLV's Artemus W. Ham Hall

In this retro-futuristic interpretation of a classic one-ring circus., strongmen and acrobats perform alongside a galloping metal horse. September 22, 7:30 p.m., $20-$50, 702-895-2787. -C. Moon Reed

Metro Boomin at Light

The producer extraordinaire just hit a new career high: Wrestling legend Ric Flair used the track “Ric Flair Drip” (with Offset and 21 Savage) when he walked down the aisle for his (fifth) wedding. It’s doubtful someone will get hitched at Light Saturday, but Metro will definitely make this one boom. September 22, 10:30 p.m., $20-$30. –Brock Radke

Monkey Mixer at Two Locations

It looks like a cement truck, but it’s actually a 2,400-gallon shaker filled with a Monkey Shoulder Scotch Whiskey cocktail. You get to help empty it. September 22 & 23, Saturday, 4 p.m., Total Wine, 5720 Centennial Center Blvd.; Sunday, 10 a.m., Twin Peaks, 9510 S. Eastern Ave. –Spencer Patterson

Quintron & Miss Pussycat at Bunkhouse Saloon

Quintron is a multi-instrumentalist; his wife Panacea Pussycat is a puppeteer. Together, they’re one fierce New Orleans dance-noise duo. With Cody Brant, Chocolate Jesus 702. September 25, 9 p.m., $10-$15. –Leslie Ventura
