Klein; a program of woman musicians and performance artists at SIGNAL; a symposium about art and technology at the New Museum; the world premiere of an opera-novel about a spy in South Asia by Robert Ashley at the Kitchen; and a conversation about Basquiat and queer contemporary art.

Talk: Tauba Auerbach

San Francisco-based artist Tauba Auerbach will give an artist's talk discussing the glass sculptures she made during her UrbanGlass residency, which take the helix form as a point of departure for an investigation into the fourth dimension. These sculptures are included in her solo show "Projective Instrument," at Paula Cooper through Feb. 13.

UrbanGlass, 647 Fulton Street, Brooklyn
