On April 29, from 4:30 to 6:00 p.m., the Gustavus Dance department will be performing an improvisational dance piece. The dance is set by Jeffery Peterson and Melisa Rolnick in the Linnaeus Arboretum and will feature dancers from all levels of technique classes. The performance is part of the department’s annual celebration of World Dance Day. This year it will also coincide with Arbor Day. Everyone is encouraged to watch; no tickets are required.
