In this episode of On Art, we visit the studios of Vinita Dasgupta and GR Iranna, in hopes of learning what it takes to make an innovative artwork. Also on the show, we take a trip around Delhi's Lodhi Colony and Tughlakabad, where street art has turned these colonies into larger-than-life museums. And in art news, we see why modern Indian art makes a strong showing in the New York auction circuit.
