About a dozen years ago, at a Pina Baush dance performance at Brooklyn Academy of Music, I had something close to a religious experience. It was hard to describe – but the dancers, encircling a massive pile of red carnations, created such an ecstatic movement of beauty and wonder and celebration that I felt as if I had entered a dream. A delightful dream. Cirque Eloise , the Candian company whose piece Rain I saw today in Princeton, just took me on a similar trip. The piece, which ended in a joyous chaotic childhood romp in a simulated rainstorm was breathtaking. Wow.
