So glad to see this topic finally picked up in this context. We have been having a big discussion about this over at Culturebot.org, a website devoted to contemporary performance:
The artists Nikki Columbus refers to – Taylor Mac, ERS, The Civilians, Maria Hassabi, et al – are all artists we cover on a regular basis, and have covered for years. (We launched almost 8 years ago to the day).
We would love to facilitate dialogue between visual art performance and contemporary performance and have started discussions about how to create a parallel festival that embraces the kind of work we are passionate about but is excluded from Performa.
