Between Martin Luther King Jr. weekend and Barack Obama’s swearing in, this week is definitely one for dancing and getting spirited, and L.A.’s got a slew of celebratory choices. Friday, Jan. 16, Hands Up LA 2 offers its second bash at Cinespace, with everyone from Franki Chan, DJ Lolli and Swedish Egil on the main stage to cleverly named electro headz like Bul!m!atron and Killed by Synth in the front room. The ciggie-slurping hot mess masses will enjoy mash-ups on the smoking patio, which will be packed since it’s an 18-and-over event. 6356 Hollywood Blvd., Hlywd. RSVP at http://losangeles.going.com/handsupla2. The next night, Sat., Jan. 17, it’ll be all about unity at Connected V, a megatechno/house/trance-a-thon featuring Frankie Bones, Dyloot, Jason Blakemore, Classixx, LAZRTAG, Eli Smith, Joaquin, Twisted Individual, APX-1, Dirty Deeds, Crackerjack and oodles more. Location TBA. (See Myspace.com/connectedfully for more info.) And finally, most of us will be glued to our TV sets on Inauguration Day, Tues., Jan. 20, but those looking to party after may want to head to the Art of Change Inaugural Ball. Obama’s speech will be broadcast on TV screens surrounding the space, and headliners The Mutaytor promise “special surprises” in honor of our new prez during their rhythmic spectacle. The Crystal Method have been announced as a “surprise” bonus around midnight, along with sets from DJ Wolfie and Motion Potion. At the Mayan, 1038 S. Hill St., dwntwn.
