The headlining contingent at this year's Bonnaroo Festival will feature a couple of well-known veteran artists.

The four-day event -- set to take place June 11-14 in Manchester, Tenn. -- unveiled a lengthy list of the first performers booked for its latest edition, led by headliners Robert Plant and Billy Joel. Bonnaroo 2015's biggest names also include Mumford and Sons, Deadmau5, Kendrick Lamar, Florence and the Machine and My Morning Jacket.

Bonnaroo's known for being one of the more eclectic festivals on the circuit, and this year's lineup doesn't disappoint; other acts already confirmed to perform include Slayer, Earth, Wind & Fire and Tears for Fears.

Impressive as this opening salvo of acts might be, it's just the beginning for Bonnaroo; organizers ultimately intend to have more than 125 musical acts and 20 comedians on the bill, which will also include a pair of 'SuperJams' -- one featuring some of the bigger stars at the festival, and the other, hosted by Ed Helms, with a bluegrass bent.

You can check out the official announcement video above for a more comprehensive look at who's slated to appear, and head over to the Bonnaroo site for further information. Tickets, which include general admission and VIP packages, are scheduled to go on sale Jan. 17.
