The 7th annual "Roots picnic" is going down in Philly and in the past has featured acts like Kid Cudi, Wale, Solange, and of course The Roots.

This year they've added on Janelle Monae, and Snoop dogg, Lion, errrr Calvin Broadus or whatever he's calling himself these days haha.

The Roots picnic is def one of those events that people from all over the country flock to every year, and I don't think this year will be any different. 

I might have to take a day off for that one, you never know who they'll bring out since they became the house band at the tonight show!
