Bonnaroo took an unconventional (and for some, frustrating) method towards announcing their lineup, forgoing the lineup poster in favor of a Weird Al Yankovic-hosted variety show/telethon with special guests and a toll-free number that revealed confirmed bands one by one to each caller. After a few hours and some bizarre sketches (at one point, comedian Chris Gethard bobbed for meat at the request of two callers), we have a full lineup, and it’s a big one.

This year, Paul McCartney, Mumford & Sons, and Tom Petty & The Heartbreakers headline what has turned out to be an unbelievably stacked lineup. Among the excellent bands playing at the festival are Wilco, The National, The Lumineers, David Byrne & St. Vincent, Passion Pit, Grizzly Bear, Beach House, Cat Power, Gov’t Mule, Sam Bush & Del McCoury, Dwight Yoakam, Dirty Projectors, Trombone Shorty, Two Gallants, Preservation Hall Jazz Band, The Tallest Man On Earth, DIIV, Ariel Pink’s Haunted Graffiti, and Jason Isbell & The 400 Unit. And that’s not even half of the lineup.
