Sure. I talked to my friend that works for GV today, and he said that the Descendents were playing. I asked him who else and he said: Phoenix (who are not headlining) the Yeah Yeah Yeah's (which Spooks already confirmed), Blur, and Daft Punk (whom he mentioned to me a few months ago as one of the headliners).
You know what GV employees are famous for? Talking to their friends who post on message boards about the headliners.
