Pearl Jam frontman Eddie Vedder went solo on Friday (07Jun13) for a special performance at a benefit for Ben Affleck's Eastern Congo Initiative.

The rocker took to the stage to play an acoustic set at the Los Angeles home of talent agent Patrick Whitesell, who was hosting a dinner to raise funds for the Argo director's community-building charity to help the people of the African country.

Affleck himself was among the star-studded crowd, along with his actress wife Jennifer Garner and former U.S. President Bill Clinton.
