The San Francisco Museum of Modern Art has a regular podcast (sfmoma.org/podcasts), featuring interviews with and profiles of artists whose work is currently being shown. The most recent SFMOMA podcast, dated December 2005 – January 2006, features amid the commentary a newly commissioned performance by cellist Joan Jeanrenaud, formerly of the Kronos Quartet, inspired by artist Bruce Conner (MP3). It’s a lovely miniature, layering bowed tones, transformed apparently by digital delay, and plucked patterns that push against the beat. The podcast is just over 15 minutes long, and the Jeanrenaud piece begins at the 4:14 spot. (One warning: the narration is of the sort that employs the word “assemblage” like it’s still on loan from the French.) More on Jeanrenaud at jjcello.org.
