The Bonnaroo Music Festival is back again and its lineup is more packed than ever with the biggest stars in the music industry. From Lizzo and Lana Del Rey, to Young Thug, The 1975, and Miley Cyrus, the list of performers for this year's Bonnaroo is roo-diculous. Tickets go on sale on January 9 at 12 p.m. EST.

The four-day festival's enormous well of talent is split evenly across periods. Headlining the first day (June 11) is the legendary Grand Ole Opry, the weekly recurring performance set of famous country musicians that pay homage to the genre's roots. Hosted by Opry members Old Crow Medicine Show, the headlining set will include music from Steve Earle & the Dukes, Morgan Evans, Ricky Skaggs, Riders in the Sky, Molly Tuttle, Ashley Monroe, Wendy Moten, and more. The Opry Square Dancers will also be there. Rising rap group 99 Neighbors, singer and guitarist Briston Maroney, and others follow Grand Ole Opry to round the opening night's performances.

Progressive metal band Tool is one of the headliners of Bonnaroo's second night (June 12). They released Fear Inoculum last August, their first album since 2006's 10,000 Days. Seeing them play Bonnaroo is cause for some serious celebration. Aside from superstar Cyrus who recently hinted at dropping some new music in the near future, DJ Bassnectar rounds out the second night's highest billed artists. The 1975, Megan Thee Stallion, fiery stomping rap group Run the Jewels, and more are set to play as well.

Night three (June 13) of Bonnaroo's four dates is headlined by Lizzo, who's having the first of many moments thanks to "Truth Hurts," "Juice," and other pop smashes; Australian DJ Flume, who has collaborated with artists like Lorde, Vince Staples, slowthai, and more in the past three years; and rock supergroup Oysterhead that's comprised of guitarist Trey Anastasio from Phish, drummer Stewart Copeland of The Police, and bassist Les Claypool of Primus. Denzel Curry, J.I.D, Nelly, who will be performing his Country Grammar album in full, and more will appear.

The last night of the festival (June 14) has psychedelic collective Tame Impala, Lana Del Rey, and Vampire Weekend at its top slots. Young Thug, singer Grace Potter, Celtic punk band Flogging Molly, and more will bring the electric energy to the final day.

Last year's Bonnaroo Music Festival was one for the ages. Brockhampton, Post Malone, Kacey Musgraves, Solange Knowles, and more all ripped the stage.
