The Swarm exhibition at the Fabric Workshop and Museum in Philidelphia juxtaposes new media generative artists with well known contemporary artists. Featured in the show are some artists with connections to the Walker including Julie Mehretu, Sarah Sze and Matthew Ritchie who are in the exhibition with less established artists Casey Reas and Jason Salavon. I found the Walker’s site had rich information about several of the artist featured in the Swarm exhibition.
Mehretu’s collaboration with entropy8zuper! was featured in the exhibition How Latitudes Become Forms and is currently hosted by the Walker. In 2003 the Walker showed Julie Mehretu: Drawing Into Painting. It looks like the catalog is still available as well.There are also three segments of an opening day talk featuring the artist available through Art on Call. (1, 2, 3)
