The techno-aesthetic Ingenuity Fest has always drawn inspiration from the Kokoon Arts Club, the early 20th-century circle of artists and innovators who pioneered Modernism in the Midwest. Tonight, the Fest channels Kokoon’s Bal Masque, the collective’s annual costume ball. Like that soirée, Bal Ingenieux offers access to some of the region’s boldest performance and installation art, now collected in the historic Halcyon Lodge in Ohio City. There’s a similar enthusiasm for dressing up too: Visitors are encouraged to wear a mask, or pick one up at the door. Among the should-be-memorable moments, legendary DJ Rob Sherwood — the original kingpin of the city’s club scene — returns for a rare evening-long set, and the musicians of Cello Fury put their monster strings and drums to use in an energetic performance. Chris Yanc, “digital graffitist,” previews his project for this summer’s Ingenuity Fest; and sound artist James Murray creates an interactive sound environment. There’s lots more too; after tonight, you’ll hardly be able to wait until the big weekend in September. Admission is by timed ticket. A 6 p.m. entry goes for $100, 8 p.m. is $40, and 10 p.m. costs $20; different perks come with each tier. Get them at the door or online, where you’ll find more information.
