Midnight Circus founders Jeff Jenkins and Julie Greenberg are up to their old tricks, bursting the bubble of stuffy intellectual theater as they did in the late 90s. Here the targets are B.J. Jones, artistic director of Northlight (who never appears onstage), and actress-singer Alexandra Billings (who does, playing the diva to the hilt). Expert clowns, Jenkins and Greenberg pretty much steal the show, though not because they hog the spotlight: everyone gets time, including the troupe’s aerialists, contortionists, jugglers, and “karate guy.” Most play their gigs for laughs, so there’s none of the stultifying reverence sometimes reserved for circus feats. Mitchell J. Fain is killing as Northlight’s supposed representative; Mars Williams’s acid-jazz group Liquid Soul provides the inventive accompaniment. Through 3/12: Thu-Fri 7:30 PM, Sat 3 and 8 PM, Sun 2:30 PM, Northlight Theatre, North Shore Center for the Performing Arts, 9501 Skokie Blvd., Skokie, 847-673-6300, $34-$54. Closing.
