TV On The Radio, Public Enemy, the Black Keys and Santigold are among the acts handpicked by The Roots to play the band's second annual hometown "Roots Picnic" on June 6 at Festival Pier in Philadelphia. Public Enemy will perform the classic album "It Takes a Nation of Millions to Hold Us Back" in its entirety backed by The Roots and Brooklyn-based Afrobeat band Antibalas. The Roots will also play two sets, opening and closing the festivities. The "Roots Picnic" runs from 2:00 pm - 11:00 pm.

The Pipes featuring Zoe Kravitz and Busdriver are also set to play on the main stage, with DJs Cash Money and Jazzy Jeff spinning sets in between the bands. Writtenhouse, Back to Basics, Making Time, Busdriver, Kid Cudi and Asher Roth will all play on a second stage.

Last summer, Public Enemy did several live performances of "Nations" in London and Chicago, but the Philadelphia show will be the first time the group will reinterpret the album with a live band. Public Enemy will play live with The Roots on "Late Night with Jimmy Fallon" on Monday (March 16).

Last year's inaugural "Picnic" was face-melting hot, both in temperature and tunes. Diplo, Gnarls Barkley, the Cool Kids, Deerhoof, DJ Jazzy Jeff and Sharon Jones & the Dap-Kings all performed along with The Roots.
