You probably don't think of Netflix as a go-to place for music documentaries beyond Taylor Swift's tour movie, but it's determined to burnish its image. The service has teased the April 17th debut of a previously rumored documentary on Beyoncé's much-hyped performance at the 2018 Coachella festival -- conveniently, just ahead of the 2019 festival's second weekend. You won't find a trailer or other details, but there's little doubt that the teaser is a callback to both the yellow outfits Bey's team wore as well as the launch of her Homecoming Scholars Awards Program at the same time.
