Novel ideas are hard to come by in a local music scene where repetition and imitation are the norm. One of the exceptions is the annual Vanishing Show, a unique live music experience unlike your typical bar gig, concert, or festival. The DIY music event put on by DJ and community organizer A Claire Slattery is a mobile party and movable indie rock feast that roams Tempe's Maple-Ash-Farmer-Wilson neighborhood one night every spring since 2015. Here's the setup: Slattery will post a starting location online (typically a house) where attendees can gather. A local band will perform a 20- to 30-minute set; then, the next location is announced just before they wrap up. The crowd then "vanishes" and heads over to the new spot by cycling or walking to catch the next band. Operating on a shoestring budget with nary a permit, the Vanishing Show and its audiences often play a cat-and-mouse game with Tempe cops, who have shut down the event a few times in the past after noise complaints. Their party-pooping isn't going to stop Slattery, who's already planning next year's Vanishing Show.
