Donald Glover, who raps under his stage name Childish Gambino, is back — almost: After stepping away from the music world for a bit, the actor/comedian/rapper teased new music in an app he released Sunday night.

The free app, called PHAROS Earth, seems to announce an upcoming festival in Joshua Tree, California that will take place Sept. 2-4 and feature “new music” and a “full album experience” from Glover. Tickets cost $99 and include a camping space for those 21 and over. The presale begins June 24 at 9 a.m. PT on the app and they go on sale for the general public June 27 at 9 a.m. PT.

Glover last released an official album in 2013 with the Grammy-nominated Because the Internet and put out both a mix tape, STN MTN, and EP, Kauai, within a span of two days in 2014.

Since then, he’s appeared in movies like Magic Mike XXL and The Martian and continued to star in Community until it last aired in 2014. Most recently, he created FX series Atlanta, set to debut this September.
