Four-day music, Tennessee-based music festival Bonnaroo has been sending out clues via their social media feeds as to who will play this year's fest. Last year's headliners included Paul McCartney, Tom Petty and Mumford & Sons (who had to cancel, with Jack Johnson filling in).

Today's clue? A picture of Philly.


Who could the Philly artist be? I immediately think the Roots, but there is some creative guessing in the comments. What about Dr. Dog, who recently played two to-capacity shows at the Electric Factory? A co-worker pointed out that the picture is taken from West Philly. Was the headliner possibly born and raised there (i.e. Will Smith)? My favorite guess from the commenters is the Eagles.

Who do you think it could be?
