Lee Walton's "Experimental Project" at Art in General is a sort of walking cacophony. It consists of a packet of cards, each with brief instructions that set you off on a situationist drift or do-it-yourself performance. A few weeks ago, one card sent you to a marvelous Asian store on Lafayette Street, where you were instructed to look "inside large music book on the top shelf." A slip of paper then directed you to buy a lottery ticket and take it to a parking lot where you were sent to an OTB parlor and then led to a Chinese cardiologist and so on. This week's instructions read, "Nancy Whiskey Pub. Lispenard at West Broadway. Inside pocket of red jacket."
