In case you missed it over the weekend, the folks behind Launch revealed the lineup for their music festival, which has expanded to two days this year, on Saturday, Sept. 7 and Sunday, Sept. 8 at Cesar Chavez Plaza. Headlining will be mash-up and digital sampling hero Girl Talk, who puts on a crazy live show, and Las Vegas radio-rockers Imagine Dragons, who are getting crazy airplay on at least three stations in Sacramento and are just absolutely blowing up right now (that song “Radioactive” is everywhere: TV commercials, movie trailers, everywhere). For sure one of the shockers on the bill is Rocket from the Crypt, a legendary rock band from San Diego that was originally active from 1985 to the mid-‘00s. Other national (and international) acts booked for Launch are Minus the Bear, Blonde Redhead, Van She (flying in all the way from Australia!), Grieves, Cults, Surfer Blood, Doomtree, Geographer, Family of the Year, P.O.S., Gold Fields, Dessa and Turquoise Jeep. Some very lucky locals will also join the bill for what may be the gig of their lifetimes, congrats to Exquisite Corps, Doom Bird, Life in 24 Frames, Paper Pistols, DLRN and The Bell Boys. Two-day passes are on sale now, so support rad things, Sacramento, or else we won’t have rad things anymore! It’s that simple. Hit up Launchsacramento.com for more information. Launch actually kicks off on Sept. 4 with a party at the MARRS Building that for now is top-secret, but will likely be all sorts of rad. On Sept. 5 the party moves to Ace of Spades and on Sept. 6 there will be a giant fashion showcase at an undisclosed location. Details may be sparse on the events leading up to the two-day shebang at Cesar Chavez Plaza (a little suspense is fun), but what we do know is that Launch 2013 is looking pretty damn good already.
