At 3 pm today, a crew of choreographer-dancers took the stage of the Bryant-Lake Bowl Theater in Uptown Minneapolis for what might have been the surprise dance event of the year. Middle of the afternoon on a Wednesday, for one thing. And then the fact that along with such creative local talents as HIJACK dance troupe, Galen Treuer, and Jin-Ming Lai, the stage is being graced by avant-garde stars Eiko and Koma. A Japanese duo living in New York City, Eiko and Koma performed this fall at the Walker Art Center, this summer at the American Dance Festival, and at the 100th anniversary of the Japan Society in New York. The event, called the 9×22 Dance/Lab-Special Editon, is named for the modest dimensions of the BLB stage. But there’s nothing modest about the BLB’s ambitions to host more significant events like this–check their calendar frequently to avoid missing out on the equivalent, for dance and theater fans, of seeing Nirvana at the 7th Street Entry 16 years ago.
