The Bonnaroo Music and Arts Festival has added over a dozen musical acts, including Public Enemy and Ani DiFranco, and a full comedy program, including Jimmy Fallon, to its 2009 event. Bonnaroo will be held from June 11-14 on a 700-acre farm in Manchester, TN, 60 miles southeast of Nashville.

Other musicians added include reggae artists The Itals and Wailing Souls, African musicians Amadou & Mariam, underground rapper Murs, metal bangers Shadows Fall and High on Fire, R&B ingénue Janelle Monáe, electronic soul duo Pretty Lights, bluegrass guitarist Tony Rice, and indie-world buzz bands Passion Pit, Hockey and White Rabbits.

Bonnaroo will also present a host of national headlining comics in its ever-popular seated, air-conditioned comedy venue. In addition to Fallon, Triumph the Insult Comic Dog will present “Bonnapoo 2009,” a variety show with music, stand up, classic clips, unaired material, interviews and insults. Also on tap is “An Evening with The Daily Show” featuring correspondents John Oliver, Rob Riggle and executive producer Rory Albanese.
