I found this great news in an email from the Merce Cunningham Trust today:
The Merce Cunningham Trust and NYU's Tisch Dance and New Media Program proudly announce a new collaborative program to live stream and record Cunningham Workshop Showings. Paul Galando, faculty and director of the department, will mentor the Dance and New Media Fellows as they live stream workshops from New York City Center Studios in multi-cam HD.
The most recent workshop, City Center EVENT (2014), may be streamed here. I haven't had time to watch it yet, but I'm excited!
