As Pacific Northwest Ballet revs up for its upcoming triple bill devoted entirely to the works of William Forsythe, the company will live stream a special lecture-demonstration with the groundbreaking choreographer tonight on its website. The evening includes a candid interview of Forsythe by artistic director Peter Boal, an up-close rehearsal with PNB dancers and a Q&A session with audience members. The performances, which run from March 13-22, feature Forsythe classics The Vertiginous Thrill of Exactitude and In the middle, somewhat elevated, as well as his 2012 ballet New Suite, a series of pas de deux that have been individually reworked for PNB. Tune in tonight to PNB.org/Live at 6:30 pm PST. For tickets to see the lecture demonstration in person at Seattle's Marion Oliver McCaw Hall, click here.
