For August Tye, the Hyde Park School of Dance is a family affair. "I love the students, the families, seeing what dance does for people," she says. Tye's 9- and 13-year-old daughters will be performing in the school's upcoming 20th-anniversary show, "En Avant," while her husband, singer Wilbur Pauley, tweaked the score for her premiere, Lorelei. The blowout lineup next weekend also includes guests from the Joffrey, the Joel Hall Dancers, and the Paul Sanasardo Dancers.
