UC Berkeley is renowned for many things. It is a great university, probably the greatest public university in the world. It was the home of the free speech movement with continuing impacts on the community and world at large. It's campus is a wonderful with its lawns and noble trees is an urban retreat. AND it may be home to one if the best arts presenters in the US. Cal Performances. I depend on Cal Performances to present something notable every week. As I write this, the Joffrey Ballet just finished a run, the was an Eco Ensemble concert of new music, Hubbard Street Dance is in town tonight, flamenco next week...on the negative side is that if you don't know about it and are visiting Berkeley you might miss it.
