Snoop Dogg will headline the Roots' annual music picnic this May. The Legendary Roots Crew will host and back Uncle Snoop at this year's picnic, scheduled to hit Philadelphia's Festival Pier at Penn's Landing.

The newly announced lineup features more than a dozen acts in total, including Janelle Monáe, Jhené Aiko, A$AP Ferg, Biz Markie, Rudimental, Just Blaze and Action Bronson.

As has been the way of various music-related marketing tactics this year, Roots drummer Amir "Questlove" Thompson revealed the picnic performance list via video announcement Monday (March 3). In the minute-long clip, Quest uses flash cards to share the show roster (while getting his hair braided).

Besides their annual music party, the Roots confirmed work on a new concept album, And Then You Shoot Your Cousin, and recently began tenure as house band for NBC's The Tonight Show starring Jimmy Fallon.

The 7th Annual Roots Picnic takes place Saturday, May 31. Tickets go on sale Friday (March 7).
