Beyoncé's 2018 Coachella performance is widely known as Beychella.
Beyoncé headlined the Coachella Valley Music and Arts Festival on April 14 and April 21, 2018. She became the first Black woman to headline the festival. The performance included a marching-band-inspired production, a reunion with Kelly Rowland and Michelle Williams, and appearances by Solange Knowles and Jay-Z.
Netflix released Homecoming: A Film by Beyoncé on April 17, 2019. The documentary combines concert footage with behind-the-scenes material about rehearsals and creative planning. A live album titled Homecoming: The Live Album was released at the same time.
“Beychella” is an informal media label, not the official title of the documentary. Homecoming is the film's title, while the performance itself is the event commonly identified by the nickname.
