Playing to a small crowd of lucky Triple J radio contest winners and industry personnel, Ben Harper delivered an hour long acoustic set down under. He was joined on the Pearl Jam tune "Indifference" by none other than PJ's lead singer, Eddie Vedder, who was in the area doing some shows with Neil Finn. Virtue Oz taped the show for a webcast to be aired on Thursday at 8:00pm (in Australia). That's 3:00am Los Angeles time! Click here to watch it.
