Bonnaroo & Firefly Lineups Revealed: Red Hot Chili Peppers and Mumford & Sons to Headline Popular Summer Music Festivals [FULL LIST]

The highly anticipated lineups for the 2013 Bonnaroo Music & Arts Festival and Firefly Music Festival were revealed yesterday and the "red hot" headliners are no longer keeping "mum".

Bonaroo Music & Arts Festival will take place on June 13 - June 16 this summer and stepping out of the "cave" and into Manchester, Tennessee to headline will be Album of the Year Grammy winners Mumford & Sons along with Tom Petty & the Heartbreakers, and first-time Bonnaroo performer Paul McCartney.

The rest of the Roo lineup, announced by comedian Daniel Tosh yesterday, doesn't disappoint with 100 other performers including The Lumineers, Passion Pit, Pretty Lights, The xx, Of Monsters and Men, Macklemore & Ryan Lewis, and yes even R. Kelly joining in on the unforgettable Bonnaroo experience. Check out the entire lineup on Bonnaroo's website here.

Although newcomers to the summer festivities, Firefly Music Festival, "The East Coast's Premier Music Experience" in Dover, Delaware offers a lineup that competes with the vets. Red Hot Chili Peppers will headline the June 21-23 fest along with Tom Petty & the Heartbreakers. If you can't make it down to Tennessee for Petty, here's a second chance!

Other artists featured include Vampire Weekend, The Yeah Yeah Yeahs, Foster The People, Calvin Harris, The Avett Brothers, Dispatch, MGMT, Ellie Goulding, Imagine Dragons, Matt & Kim, and Zedd to name just a few.
