UPDATE 1/4: Bonnaroo shared one more clue before their 2019 lineup drops. See it, along with the previous clues, below.
Bonnaroo 2019 happens June 13-16, and while the lineup is still TBA, the festival posted a few clues on their Instagram that have all been collected in a thread on the r/Bonnaroo Reddit. Acts listed as "confirmed" ("Roo clues with indisputable answers, Artist confirmations, Bonnaroo confirmations") include Parquet Courts, Gojira, Little Simz, The Nude Party, Shovels & Rope, Clairo and ZHU, and it's also "semi-confirmed" ("Roo clues with unclear answers, Leaks, Info from reliable sources") that The Avett Brothers are playing. There are of course lots of rumored acts listed too, ranging from Arctic Monkeys to Foo Fighters to Phish to Post Malone to Robyn, and all of this is speculative/to be taken with a grain of salt until the official lineup is out. Stay tuned!
Tickets will go back on sale again soon too (the presale just ended last night).
