Otto Ramstad and Olive Bieringa are a couple who also create public performance works as The Body Cartography Project. They’ve performed and taught around the country, on both coasts and internationally. 3-Minute Egg dropped into a fundraising party at their Minneapolis house, where they and other dancers performed snippets of the Body Cartography’s ambitious Holiday House. This week, the Body Cartography are presenting new work at the Coil Festival in New York.
