Beyoncé headlined the Coachella Valley Music and Arts Festival in 2018. Her performances took place on April 14 and April 21, 2018, at the festival in Indio, California.
She had originally been scheduled to headline the 2017 festival, but her performance was postponed after doctors advised her to rest during pregnancy. Her 2018 set became a major cultural event, featuring a large marching-band-style cast, Destiny's Child appearances, and a celebration of historically Black college and university performance traditions.
The performance was widely known as “Beychella.” Netflix released the concert documentary Homecoming: A Film by Beyoncé in 2019, and Beyoncé issued a live album with the same title. Beyoncé was the first Black woman to headline Coachella, but the answer to this question is the year, not the year of the documentary's release.
