Despite spending much of their time as Jimmy Fallon's in-house band on late night television, The Roots have announced a new album set to drop in 2013. On top of all this, the group always manage to put together a solid lineup for their annual curated festival in Philly. The "Roots Picnic", now in it's 6th installment, always sports an interesting and varied lineup of artists. Last year saw Wale, Kid Cudi, De La Soul, and Rakim take the stage, as well as The Roots themselves, who often serve as the backing band for at least one of the performers.

The Roots have announced today the lineup for 2013's festival. ?uestlove and Black Thought have hand picked the artists, Naughty By Nature, Grimes, Gary Clark Jr., Macklemore & Ryan Lewis, Solange Knowles, Joey Bada$$, How to Dress Well, Sonnymoon, Jennah Bell, Trinidad Jame$, Robert Glasper, Lushlife, DJ Premier, Hit-Boy, The Gaslamp Killer and araabMUZIK.

The Roots will also perform a set at the show, and will back up Naughty By Nature for their performance. 

Quest commented on his process for selecting artists for the festival, "The hardest thing is catching acts that are just getting buzz so you can get them on the cusp," said ?uestlove. "I thought instantly that Macklemore and Ryan Lewis were going to be poppin. And just on a hunch, I was like, 'Alright.' We hit them and they agreed. Sure enough, after the album came out, they just became unstoppable."

The Roots Picnic will take place at Festival Pier at Penns Landing in Philadelphia on June 1st.
