This week (Thursday, June 17th), The Marketplace of Ideas features a conversation with David Toop, composer of sound, writer about sound, curator of sound and research fellow at the London College of Communication. His works in text include Ocean of Sound, Exotica, Haunted Weather and the Rap Attack books. His latest is Sinister Resonance: The Mediumship of the Listener, which explores the sound of silent art.

The Marketplace of Ideas airs every Thursday, five minutes past noon.
