About midway through Beyoncé’s performance at Coachella last year, the booming, disembodied voice of the motivational ad-libber DJ Khaled proclaimed that, henceforth, the music festival would be known as “Beychella.”

Unlike almost everything else Khaled pronounces in his music and on social media, the statement hardly felt hyperbolic: This was a career-defining performance for Beyoncé, who became the first black woman to headline the festival since its debut in 1999. For nearly two hours, she and an astounding cast of dancers, singers and musicians wove together a beloved, unparalleled collection of hits and deep cuts, interpolated with music from the “Dirty South” and civil rights activists like Nina Simone — served against the visuals and iconography of historically black colleges and universities.

A year later, as the second weekend of Coachella approaches, the memory of Beychella looms large; no accumulation of star-studded guest appearances or secret movie reveals in the desert from this year’s lineup can gin up the same excitement. Which is what makes the Wednesday release of the Netflix documentary “Homecoming” — accompanied by the surprise release of a corresponding live album — even more of a coup. She may not be headlining this year, but we’re all going to pay attention and bow down anyway.
