This year's lineup is absolutely stacked. The headliners are Childish Gambino, Ariana Grande, and Tame Impala, as well as Janelle Monáe, The 1975, BLACKPINK, Khalid, Billie Eilish, and Kid Cudi. Solange was also scheduled to perform, but had to pull her set due to production delays. On the plus side, Rihanna and Donald Glover will be premiering their mysterious new project, Guava Island. Oh, and Kanye West will be hosting his popular Sunday service.
