Unbeknownst to most Milwaukeeans, the city harbors a small band of street performers passionately dedicated to the traditions of vaudevillian comedy, lying on broken glass, and stripping off clothes slowly to music. Dead Man’s Carnival has been playing for the bar crowd since 2007, preaching the gospel of the underground circus as part of a growing grassroots movement that stands squarely against canned corporate entertainment. The A.V. Club met some of the core members at Stonefly Brewery, where they will be performing their latest two-stage, four-hour extravaganza of burlesque, cringe-inducing sideshow stunts, “fire-manipulation,” and live music on Saturday. The performers go by their nommes de cirque: Gypsy Geoff, Sir Pinkerton Xyloma, Zero The Clown, Lady Ambrosia, and Erik Bang!!!.
