This is a very brief performance of Conversation (for John O'Donohue) which is a composition that occurs when two people play ping pong separately together against the glass and a third listens.
In an interview with Krista Tippett the poet, John O'Donohue, asked, "...when is the last time that you had a great conversation, a conversation which wasn’t just two intersecting monologues, which is what passes for conversation a lot in this culture?"
