EXCLUSIVE: I’ve just gotten the info on this year’s Rainforest Foundation concert. Tomorrow (Thursday) Sting and his multi-talented actress/activist/producer wife Trudie Styler will announce an all star show for April 17th at Carnegie Hall. Guest artists will be revealed shortly, as well. In the past the guests have included Billy Joel, James Taylor, Brian Wilson, Sam Moore, Elton John, Bruno Mars, Jennifer Hudson and so on. Two years ago, at the last show, Meryl Streep even pitched in and performed. Sting has been on tour with Paul Simon (coming to MSG March 4th and 6th). No word yet on whether Simon will participate, but it seems like a good bet.
