The UW-Madison dance department?s fourth annual Summer Dance Institute is truly an international affair, with instructors and choreographers from the U.S., Canada, Brazil, Germany and Australia, and dance students from Australia, Taiwan and the U.S. This three-week institute culminated Friday night in a free performance at Lathrop Hall?s cool and comfortable Margaret H?Doubler performance space. For the most part, this cultural cross-pollination yielded great results.
