The Roots have cause to celebrate right now. Aside from completing a year of work as the band for Late Night with Jimmy Fallon, fans will be excited to hear that the Roots are actually celebrating the third annual Roots Picnic this year, with many big named guests on the bill.

The event is set to take place at Penn’s Landing in Philadelphia. This is the third year of the Picnic, which has seen acts like Kid Cudi, Asher Roth, TV On the Radio and Public Enemy in the past. This year, more guests are set to take the stage in what Questo has said will undoubtedly “top” last year’s show.   

Vampire Weekend, The Clipse, Pattern is Movement, Mayer Hawthrone, Das Racist and many others are set to perform. The event will also include a performance by Black Thought’s side project The Money Making Jam Boys. Not to be outdone, ?uestlove will also have a side project for the evening as he will team up with DJ Jazzy Jeff.

If that weren’t enough, The Roots will also bring a reunited group to the stage.

“This is a reunion we thought we would never get. We’ve been waiting to make this reunion happen for the longest. It’s so incredible I don’t even want to tell you who it is,” he said before putting on a gold rope chain and a black hat, insinuating that Run and DMC will be present.

?uestlove announced this via TwitVid, a clip that can be seen below.
