It looks like the project, which is apparently titled Guava Island, may get released as soon as next weekend, perhaps during Coachella. Fans over the past few days noticed some ads on Spotify mentioning the project. Their popular RapCaviar playlist is also being “presented by Guava Island” with one of the ads featuring audio of Gambino singing over guitar before he says, “I’ll see you at the show, everyone.” The film involves Rihanna but it is unclear if she contributed to the music as well. One ad also mentions “April 13th” which is a day after Donald Glover is set to perform at Coachella.
