It's hard to imagine now, but 15 years ago, it was a radical idea. When the San Francisco International Hip Hop Dancefest held its first production, almost no one was putting street dance in the theater. Fast forward to the present: Popping and locking are respected as legitimate techniques, b-boys tour the world with Cirque du Soleil, and the Dancefest is still going strong. This year's production sees the return of local favorites Mix'd Ingrdnts, Funk Beyond Control, and Loose Change, with the international representation held down by London hip-hop theater group Far From the Norm. Of the many companies represented, we're most intrigued by New York's Bones the Machine, which will display its "bone breaking" style of dance, and most excited about FootworKINGz of Chicago. As always, the Dancefest has an A program and a B program, which can make for a pretty tough decision at ticket time. If we were forced to choose, this year, we'd pick the A program.
