On Friday evening, Donald Glover returned to Twitter to share a link to a mysterious app called Pharos. Downloading the app revealed a countdown timer and the sense of rushing through space towards something. As the timer counted down it became clear that users were approaching earth. Now, we know what the mystery app was all about.

Donald Glover will be performing new Childish Gambino music as part of what the app calls a “full album experience” in Joshua Tree, California on September 2, 3, and 4. Fans who buy a $99 ticket are told to bring a tent to take advantage of the on site camping.

Whatever form the new music takes, it will be the first from Gambino since 2014 mixtape/EP STN MTN / Kauai. His last official album was Because the Internet released in 2013

Pre-sale for what sounds like Glover’s own three-day music festival will be available in app starting June 24 at noon ET / 9 a.m. PT. General onsale starts June 27 at noon ET / 9 a.m. PT. See screenshots from the app below and download it here to have a shot at pre-sale.
