At the center of every circus rests a 42-foot ring full of thrills, laughs and excitement, and in its new show, “42FT: A Menagerie of Mechanical Marvels,” the inventive American circus troupe Cirque Mechanics invites audiences to “Step right up, ladies and gentlemen, boys and girls” to the world of gears and canvas, pulleys and sawdust.

Described by The New York Times as “intelligently conceived and expertly executed,” the show dares viewers to leap into the circus ring and experience the timelessness of an evolving art form. Cirque Mechanics will appear for one show only at the Bankhead Theater on Sunday, Feb. 9.

As with all Cirque Mechanics’ shows, “42FT” is a unique mechanical interpretation of the traditional. The stage becomes a Big Top, filled with historic one-ring circus lore and lit up with constant action, amazement, and a showcase of wonders from a galloping mechanical horse to a rotating tent frame for strongmen, acrobats and aerialists.

Cirque Mechanics was founded in 2004 by Boston native and German Wheel artist Chris Lashua, following his successful collaborative project “Birdhouse Factory,” with the Circus Center of San Francisco. Cirque Mechanics quickly established itself as a premiere American circus, with a unique approach to performance, storytelling and staging. The company’s shows are set apart by their unique realism and a raw quality that reflects the stories of American industrial ingenuity. In “42FT,” Cirque Mechanics offers acrobatics, mechanical wonders, and a delightful bit of clowning around that brings the center of the circus ring to life.
