There is an exhibition on view right now at MoMA PS1, James Lee Byars: 1/2 an Autobiography.
My father, Simon Blackall knew Byars when they both lived in Kyoto in the mid 1960s. He photographed some of Byars's conceptual, ephemeral, performance pieces for posterity; photographs which are now part of MoMA's collection. My father and step-mother are briefly in New York so we made a field trip to PS1 which was quite wonderful.
Simon wrote about this very piece on our blog, where I am slowly illustrating his adventures.
