How has hiphop thrived so long? On Nov. 22-24 take a look at the 21st Annual SF International Hiphop Dance Fest with energized dance troupes from New York and Chicago – and to give you an idea of how global this choreography has become – Montreal and Norway. Hiphop is so major that you can see it exploding in the stately Palace of Fine Arts. Besides high energy slang/gang performances, there are master classes. Tickets start at $47.
