For this show, you’re going to want to papier-mâché yourself into a glorious costume and spray-paint that costume yellow or silver or navy blue—add some mesh! Add some rhinestones! Then, pop a few Truckers Luv It energy pills (actual product) and get your ass to Chop Suey. All the bands on this bill are perfect for Halloween, but most perfect would have to be the Ononos, a band of visually arresting light beings. Their pulsing, sexy future-synth is like standing in the spinning vortex tunnel of a haunted house—it will give you vertigo, but you haven’t had this much fun in eons.
