Shadows of Light (Music from the Seagram Murals)18.12.2008 Jim Aitchison is a composer who takes his inspiration directly from visual art. He’s currently working on a piece of music in response to Tate Modern's Rothko show. One day in December he brought The Kreutzer Quartet, Michael Thompson and Nicholas Clapton along to the exhibition to improvise amongst Rothko's Seagram Murals. The results will be performed at a special concert to take place in the space in January. We were there to ask him about the challenge of translating paint into sound.
