Belgium’s Ultima Vez stole into New Jersey with the year-old, two-hour Blush, created by Wim Vandekeybus and his international gang of totally committed performers, to an original score by David Eugene Edwards of 16 Horsepower and Woven Hand. They crashed through a projection screen made of hundreds of white strips, spilled into the audience to flirt and vomit, fornicated onstage, and cast a spell that perfectly captured the zeitgeist of the young generation. A tall, lusty blonde woman, presumably dead, stalked the stage bewailing the life she’d lost while her compatriots undressed and dressed (possibly for her funeral) and leaped and rolled and shinnied up poles and threw themselves at each other and the floor. Film of dolphins, frogs, cornfields, and hordes of nude bodies, by Vandekeybus, Lieven Van Baelen, and Jan Dellaert, amplified the juicy chaos onstage. Powerful, strange: too far away, and too soon gone.
