Never seen modern dance before? It’s possible you’ve seen Pilobolus without realizing it. Perhaps it was their 2007 Academy Awards shape-shifting or maybe one of their handful of car commercials or TV appearances on Conan or Oprah or their more recent viral hit music video collaboration with Grammy-winners OK Go.Like the opportunistic, sun-loving fungus it’s named after, this dance performance troupe gets around. Since its inception at Dartmouth College in 1971 and a longtime American Dance Festival affiliation, the Connecticut-based ensemble has flourished into one of contemporary dance’s best-known global ambassadors, having toured to more than 64 countries. Pilobolus returns to the Aronoff Center Wednesday and Thursday, as part of Contemporary Dance Theater’s Guest Artist Series. Don’t miss this revolutionary company’s elegant, witty and boundary-pushing aesthetics that celebrate the human form in unexpected ways. Don’t wait; tickets are going fast. $30-$40. 7:30 p.m. Aronoff Center. 650 Walnut St., Downtown. 513-621-ARTS.
