One of Philadelphia’s most innovative theatre companys, Pig Iron Theatre, hosts its annual benefit cabaret at The Troc tonight. The theme of the cabaret is Pignometry, or the mathematics of angles and curves, and the illustrious Miss Martha Graham Cracker and a roster of sassy performers, who have connections to the company, will be testing their intellectual, musical, and acrobatic skills. There will be a special silent auction that features items like a membership to the Fairmount Park Conservancy, tickets to Longwood Gardens, and a basket of rum. Johnny Showcase and the Lefty Lucy Cabaret will tantalize with their raucous soul revival and charismatic showmanship, and Unidos de Filadelfia will bring their world beat and Latin soul. The show will also feature performances by the Bearded Ladies Cabaret, Fantasy Grandma, Briand Sanders Junk, and more. Trocadero Theatre, 1003 Arch St., 8pm, $25-$125, 18+ – Bill McThrill
