Think of it as speed-dating for dance: Over four nights, 40 different artists each get five minutes on Joe's Pub's sliver of a stage to win over audiences. That's 10 bite-size performances from a range of companies and choreographers nightly. Statistics, and the festival's history, suggest that some are bound to be gems and others will bomb. Each night the audience selects a favorite, and the winner will receive a weeklong residency. On Sept. 13, the Top 10 audience favorites get an encore. It's a great tasting menu to kick off the busy fall season.
