Harmonic dubstepper Ill-Esha celebrates her new EP at Public Works

Honest to Tyra, one of my absolute favorite things in the world is the N-Judah Night Owl bus at 3 a.m. Where else can you encounter such a juicy cross-section of the city's nightlife players — at least the ones too broke or too cheap (or too hot, like me) to snag a cab home?

The guilt-eyed bridesmaid lured away from her bachelorette for a quickie in the bushes; electro kids still fidgety from that tragic final snort; full-throated bro-skis trying tipsily to locate the end of their sentences; post-concert hipsters screaming over their own blown eardrums, ankles swollen and bright blue from asphyxiating jeggings (still!); drooling newbie Googlers who tried so very hard to be "cool," succumbing to drowsy numbness as their $300 steampunk sunglasses slip, one lens cracked, from their acne-scarred foreheads; botched pot deals, stunned French teens, cruisy bears, fresh tweakers, gothic Lolitas, country line-dancers, really aspiring rappers, several actual hotties ... Amazing. Especially when someone busts out a boombox. All aboard our homegrown diesel-driven party train, woot woot!

NERD NITE

"It's like the Discovery Channel ... with beer!" I'm not sure if there's going to be intentional dancing at this hot monthly snarf-a-thon, but feisty cerebella should be jumpin' for these presentations: "Mars's Lumpy Bumpy Neato Magneto(sphero)," "Penguins, the True Chickens of the Sea," and "The Perilous Infirmity of Burning: The History of Neisseria Gonorrhea." OK!

Wed/17, doors 7:30 p.m., show at 8 p.m., $8. Rickshaw Stop, 155 Fell, SF. sf.nerdnite.com

PACO OSUNA

They say that minimal is dead — but it actually just got hijacked by hot Spaniards. They added some much-needed swing and even humor (not to mention a little color) to the pale-faced genre, keeping the intellectual rigor but expanding its rhythmic template. Beardy Barcelonan Paco Osuna still likes it dark and heady in a Plus8 Records vein, but he knows how to thump the floor as well.

Thu/18, 9:30 p.m., $10. Vessel, 85 Campton Pl., SF. www.vesselsf.com

RADIOACTIVITY

The monthly happy hour celebrating "the sound of low budget synthesizers, Eastern European Cold War dance parties, and the more experimental, dubby, and danceable side of post-punk" turns one year colder with special guests Dominique Leone, one of SF's best hoarders of vinyl plutonium, and Wobbly, plus residents Robots.In.Heat and Tristes Tropique.

Fri/19, 6 p.m.–9 p.m., free. 222 Hyde, SF. www.222hyde.com

SIMIAN MOBILE DISCO

Yes, the Brit duo is still here, and yes, they are still your friends. I never use the word "eargasm," because ew, but if your rocks pop for anthemic electro bombast and fuzzy blasts of bass tempered ever so slightly by devilishly insistent samples, then yes, you will have a bananas one of those.

Fri/19, 9 p.m., $18 advance. Mezzanine, 444 Jessie, SF. www.mezzaninesf.com

DUBSTEP BEAT BATTLE

Little recognized fact: the Bay has a shit-ton of excellent beats-production talent. (The recent Red Bull Big Tune and BART Series Big Battle were explosions of creativity.) Promoters Phillip Drummond and Ro Knew are unleashing the future wobble with this multiplayer rumble. Plus, it's a canned food drive for Glide — bring a tin, leave with tinnitus?

Sat/20, 9 p.m., $10/$7 with can of food. Club Six, 66 Sixth St., SF. www.clubsix1.com
