Beyoncé prepped the music design of Beychella with the band for four months to achieve the sound she wanted. Then came an additional four months of dance rehearsals. "The music and those vocals rehearsals — that's the heartbeat of the show," she explains in the documentary. "I wanted it to feel like I felt when I went to battle of the bands, because I grew up seeing those shows and that being the highlight of my year."
But that wasn't the only bit of work that went into the collegiate-focussed show. "I studied my history, I studied my past, and I put every mistake and all my triumphs of my 22-year career into my two-hour homecoming performance," the artist says. "The hours were unbelievable."
