A Merce Cunningham “Event” is by definition a one-off. It sees sections from a number of dances mixed to make a new dance. The cognoscenti can trace every phrase to its origin, but you don’t need to concern yourself with that. The whole flows. Former Cunningham dancer Dylan Crossman curates this unique MinEvent, which includes dancers from a number of companies and a discussion with former Cunningham greats Kimberly Bartosik and Gus Solomons. —L.J.
