GOD IS DAD. That was the title of Sarah Lucas's last show in New York, in which the pun-prone artist assembled an array of sculptures constructed from cast concrete forms, tacky beige nylon stockings, and random metal objects. These typically abject art pieces fit right into the body of work Lucas has been building since the early 1990s from apparently banal, everyday materials. Old, worn furniture, clothing, food, newspapers, cigarettes, cars, resin, plaster, neon lamps, and light fixtures combine to form grungy assemblages whose appearance belies the serious and complex subject matter they address.
