As of May 30, Indian sculptor Anish Kapoor’s first major U.S. retrospective in 15 years, "Past, Present, Future", can be seen at the Institute of Contemporary Art in Boston. Kapoor is known for creating huge, hyper-smooth shapes; 14 of them are included in the display.

WBUR’s Andrea Shea has gone behind the scenes with Kapoor, ICA curator Nicholas Baume, installer Kellum Scott, and others to discuss the daunting and impressive task of putting on such an exhibition.
