• Still from “Untitled (Pink Dot),” 2007

Robert Beatty was supposed to play in Chicago last week with his long-running brutal noise group Hair Police, but when tourmates and headliners Cold Cave canceled, so did Beatty and company. But Beatty, who’s based in Lexington, Kentucky, is in town tomorrow night in an arguably more interesting and satisfying mode, collaborating with experimental animator Takeshi Murata and performing a short solo set at the Gene Siskel Film Center. The event is part of the theater’s superb Conversations at the Edge series.
