Bonnaroo 2013 announced its headliners and initial lineup Tuesday. The three-day festival will take place on June 13-19 at Manchester, Tenn., and here are 20 acts you should check out at Bonnaroo.

As previously reported on IBTimes, the Bonnaroo Music Festival announced its 2013 lineup and will feature headliners Paul McCartney, Mumford & Sons, Tom Petty & The Heartbreakers and Bjork as well as some great acts including Wilco, Pretty Lights, R. Kelly, Wu-Tang Clan, The National, The Lumineers and plenty more. While the top of the lineup sells tickets, the middle is where you can find some of the best new music, and it’s a great way to discover some new artists.

For Bonnaroo 2013, seeing David Byrne and St. Vincent is a must. The duo put on a great live show, complete with choreography, as well as songs from their album, “Love This Giant,” as well as songs from Talking Heads and St. Vincent’s discography. Bjork always offers a rare spectacle with interesting art direction. Wilco is one of the best American rock bands and have a great discography with plenty of songs to choose from. If Mumford & Sons and The Lumineers are two acts that you're looking forward to at Bonnaroo, Iceland’s Of Monsters and Men should also be added to that list.

Digging deeper, Macklemore & Ryan Lewis are a surprise sensation, topping the charts while being unsigned. Their Bonnaroo appearance is one of 11 scheduled shows in America. Tame Impala’s blend of garage rock and psychedelia are a perfect complement to the hot Tennessee sun, and Billy Idol will be a fun throwback to the 1980s. There are plenty of great British bands to check out at Bonnaroo as well, including Alt-J, winner of the 2012 Mercury Prize, Foals, Django Django and Charli XCX.

Hopping back to America, Local Natives, Haim, Milo Greene and Matthew E. White are just a few of the exciting young acts to check out at Bonnaroo while Canada also gets some attention with Purity Ring and The Sheepdogs.

If you want to get out of your comfort zone, Death Grips are sure to put on one chaotic show while Araabmuzik will be a great electronic act to see, in addition to A-Trak.

The 20 acts are just a few that you may not know and there are plenty of great acts that will be at Bonnaroo. There are plenty of great comedy acts, such as Daniel Tosh and “Weird Al” Yankovic, as well as veteran indie bands, such as Passion Pit, The xx and Grizzly Bear, and exciting rap and hip hop from Kendrick Lamar and A$AP Rocky. Like any music festival, discovery is much of the fun.
