The dancer-choreographer Netta Yerushalmy has undertaken a project right up my historian’s alley: she is re-imagining the work of modernist choreographers such as Alvin Ailey, Martha Graham, and Vaslav Nijinsky. Even more up my alley: she’s pairing the dance with on-stage commentary from scholarly folk. There’s a conversation about it all at Madison Square Park on August 12, and I’m looking forward to being a part of it.
