Party catalysts Groove Armada take to the south lawn of LA's city hall. The last few years have been good to the UK-based duo, with the kitschy-awesome "Get Down" and powerhouse "Song 4 Mutya (Out of Control)" (featuring ex-Sugababe Mutya Buena) climbing the international dance charts. Local electro aficionado Jason Bentley of KROQ and KCRW joins the Armada with some of his own mix mastery.
