Where on Earth is Cedar Lake? Technically, it’s in New York City, home base for the Cedar Lake Contemporary Ballet, which Cal Performances will present this weekend at Zellerbach Hall (Bancroft Way below Telegraph Ave., Berkeley). But if the company’s physical place in the world is clear, where it is creatively is less so, as it is currently between artistic directors nearly a year after the departure of Benoit-Swan Pouffer. By all accounts, interim director Alexandra Damiani is taking the company in intriguing directions, expanding the roster with high-profile new dancers such as Navarra Novy-Williams and So You Think You Can Dance alum Billy Bell. With their emotional expressiveness and fine technique, the sixteen performers will bring depth and vigor to Jiri Kylián’s Indigo Rose; Crystal Pite’s Ten Duets on a Theme of Rescue; and Jo Stromgren’s Necessity, Again, danced to a soundtrack of music by Charles Aznavour and text by Jacques Derrida. Ticketholders can enjoy a pre-performance talk at 7 p.m. on Friday, in the hall.
