The Bonnaroo Music & Arts Festival nabbed at least one giant hip-hop act last year -- Jay-Z -- but this year, they nabbed two. Lil Wayne and Eminem are among the headliners of the four-day fest, alongside Arcade Fire and jam masters Widespread Panic.

Organizers announced the full lineup this morning, with other names including The Black Keys, My Morning Jacket, String Cheese Incident, Robert Plant & Band of Joy, Mumford & Sons, The Strokes, The Decemberists, Alison Krauss & Union Station, Florence + the Machine, Girl Talk, Primus, Big Boi, Gregg Allman and Robyn. All names below.

The 10th annual event runs June 9-12 in Manchester, Tenn., with tickets going up this Saturday (Feb. 19) at 12 p.m. (noon) EST via bonnaroo.com.

Among the festivals highlights is the collaboration between Dr. John and The Original Meters, performing their 1974 album "Desitively Bonnaroo" in its entirety. That record is the source of the festival's moniker. Dr. John will also be performing with the Black Keys' Dan Auerbach during its SuperJam tradition performance.

Notably, too, the Buffalo Springfield set will feature Richie Furay, Stephen Stills, Neil Young, Rick Rosas and Joe Vitale. Gogol Bordello's Eugene Hutz has been tapped as the curator of this year's specialty venue, Global Gypsy Punk Revue, which will likely be a late-night dance spot.

This year's headlining comedy lineup is forthcoming.
