Through the UK Drawing Research Network, I learn about Andrea Kantrowitz.
Andrea is a visual artist who wrote a paper recently about her process.
She uses a structured improvisation method similar to mine.
When I posted a response to her work, with a link to my site, she replied with links to dancer/choreographer Bill T. Jones, who she thought I could find interesting:
