Exhibition walkthrough with Dean Valentine and Hammer chief curator Douglas Fogle. Second Nature: The Valentine-Adelson Collection at the Hammer (2009) brings together for the first time a selection from Dean Valentine and Amy Adelson's generous gift to the Hammer Museum's Contemporary Collection of fifty sculptures by twenty-nine Los Angeles artists. Produced from 1995 to the present, these works capture a significant moment in Los Angeles art making, when artists began to take a renewed interest in the production of three-dimensional objects using a wide variety of media, including the handmade and the readymade, sound, video, and cast materials.
