Start planning your costume now—LA's favorite public radio station, KCRW, will host its legendary Halloween masquerade ball at the Park Plaza this year on October 25. Expect to find a labyrinth of sensory-stimulating themed rooms showcasing circus troops, DJs, ghost stories, costume contests and, of course, boogying masqueraders. This year's lineup of artists includes a DJ set by Bonobo, Tom Vek, Fool's Gold, and more, plus 13 DJ sets by KCRW's own. There will also be an array of food trucks on site to satisfy your post-dance midnight hunger. The event is 21 and over, so be sure to leave any trick-or-treaters or college freshmen at home.
