The Museum of Modern Art is stockpiling an impressive audio component on their website. Comprised of lectures, commentaries, conversations and visual descriptions, these streaming podcasts provide diverse insights into a variety of both canonical and contemporary artists. Below are a few examples of some of the podcasts I listened to:
Robert Smithson. Corner Mirror with Coral.1969
Claes Oldenburg. Giant Soft Fan. 1966–67
Nicholas Nixon. The Brown Sisters. 1993
Marlene Dumas. Chlorosis (Love Sick). 1994
These are just a few of the examples of available podcasts on the MoMA website. I would highly recommend checking out some of the other content here, here and here.
