She collaborated for many years with Suzushi Hanayagi (1928–2010), and in 2009, with director Robert Wilson and others, created a multidisciplinary live performance portrait of Hanayagi entitled "KOOL, Dancing in My Mind", which had its premiere at New York City's Guggenheim Museum. A related 26-minute documentary film by Richard Rutkowski and Wilson, with the same title as the live work and including excerpts from the Guggenheim performance, premiered on Arte TV in France and the Sundance Channel in the U.S. in 2010, and an hour-long documentary, "The Space in Back of You", including an interview with Blank, premiered in January 2012 at Lincoln Center's film festival, Dance on Camera, where it was nominated for a jury prize.
