You'd be a darn fool not to check out one of world-class dance performances in Chicago this weekend: Liz Lerman Dance Exchange presents the Chicago premiere of Ferocious Beauty: Genome, a multimedia docu-dance about genetics; UK-based choreographer Sue Davies collaborated with a linguist, a cardiothoracic surgeon, a landscape designer, and an architect on a new performance In Plain Clothes at the Dance Center; finally, catch Hubbard Street before they head off on tour: don't miss their fall season Global Tapestry at the Harris. See Slowdown for details on all three of these shows.
