Music and gadget geeks can log in and let loose at Download 2008, a three-city music festival that delivers performances from indie gods, the latest tech buzz, and — maybe best of all — free stuff. Download LA packs a load of impressive acts: get ready for the reunion of Glasgow golden boys the Jesus and Mary Chain, plus Louisiana lads Mute Math, Tapes 'N Tapes, Datarock, and Georgian guitar virtuoso Kaki King. Also popping up at the Gibson tonight are electronica/pysch-pop enigma Dr. Daniel Victor Snaith (aka Caribou) and Illinois DJ Flosstradamus. Prep for the party by visiting the festival's website and downloading exclusive tracks.
