W saw Slap! last night, about a Ukrainian artist named David Burliuk, who was a futurist in Siberia, Japan, and New York. It featured my old pal Bob Holman, full of beans & wit, and bandura master Julian Kytasty. Presented by Yara Arts Group in the small basement space on East 9th Street where Ellen Steward got her start. Well-done, informative, important, & fun: what're you waiting for? It's there til February 9.
