james lovelock and john gray in conversation tonight

An annual event, the Artangel Longplayer Conversation brings together two cultural thinkers to engage in a conversation that's inspired by Jem Finer's Longplayer, a musical composition playing in real time across the millenium.

Tonight's two speakers are climate scientist James Lovelock, author of The Revenge of Gaia, and philosopher John Gray, author of Straw Dogs. The event is sold out. But it's possible to follow the conversation on a live feed.
