Stuck in what must be one of the shadiest areas of San Diego is the Beauty Bar. Originally the Playhouse, home to the infamous Hell’s Angels, it’s now a trendy music club. The main bar area features vintage hair dryer chairs that will make you feel as if you are in an old black-and-white film featuring Cary Grant and Doris Day. Flosstradamus has its table set up in the rear and out on the patio is the stage that Chromeo will call home for the night.

By 9 p.m., the place is already filled with made-up, fashionable show-goers with drinks in hand, and there is a line out the door running down for three shops. Stepping on toes cannot be avoided, so I feel sorry for all the ladies who like looking good with their open-toed shoes. The bruises they most likely received would serve as a welcome reminder for the sets that ensued.

10:10 p.m. rolls around when Dave 1 and Pee Thug of Chromeo take the stage. Because of a noise curfew that restricts loud music on the patio, Chromeo is opening for Flosstradamus.

The patio is packed. It is hopeless to move, but I somehow find a way to the back corner where the view isn’t half-bad. In front of me is the merch table, so I don’t hesitate to pick up a Chromeo tour shirt as well a pair of very hip, $5 Flosstradamus glasses.

Chromeo ran through a high-energy set, playing tracks from both “She’s In Control” and their latest album, “Fancy Footwork.” Mid-set, the guys threw down a guitar-only, somehow extremely relevant cover of Outfield’s “Your Love” that transitioned into Journey’s “Any Way You Want It,” which finally worked its way into “Mercury Tears.” For the finale, “My Girl Is Calling Me (A Liar),” Dave invited anyone on stage and soon all you could hear was the song and all you could see were hot, sweaty people dancing on the stage as Chromeo disappeared into a blob of humanity. After, they stayed on stage to speak and take pictures until all fans had received their fill.

I made the mistake of thinking Chromeo’s audience situation was the worst it could get. At least Chromeo was outside. Flosstradamus was inside a poorly ventilated portion of the bar, where people were crammed shoulder-to-shoulder with no obvious escape route, but no one had a problem. The best way to make room for themselves was to dance and my God, dance they did.

Two hours of booming beats ranged from the old school to the new school and everything in-between. Mixing MIMS’ “This Why is Why I’m Hot” into the Prodigy’s “Breathe” is something to expect from their set. They ran the gamut on genres, time periods and styles. Flosstradamus doesn’t seem to care about what is hot and trendy right now; instead, creating a new trend that allows punker kids and club-kids to share a space, dancing to incredible mixes.

I cannot count the number of times I said “Oh my God, this song?! Awesome,” as I stood next to the table and did my best to shuffle my feet in an appeasing manner. Ending the show with Weezer’s “Say It Ain’t So” brought everyone together to chant in unison the unforgettable “say it ain’t so-a-whoa-a-whoa” and closing with the mash-up that gave them a name, Sigur R
