U2 has never performed at the popular Coachella Music Festival in the California desert, but Bono got his feet wet there on Friday night by doing a brief solo performance with the Belgian-Congolese artist, Baloji. It happened at a Rolling Stone-hosted event with the Diesel and Edun fashion houses. As best we can tell, it was just a jam session that Bono sang a few made-up verses over. Jimmy Iovine, John Legend and P. Diddy were just some of others who were on hand. Here's a photo album from the event, and below is a short video from Rolling Stone.
