On June 27, 2015, David Byrne — never one who shies away from a grand gesture — paired 10 color guards with well-known musicians, including the Beastie Boys' Ad-Rock, Devonté Hynes, tUnE-yArDs and St. Vincent, on the stage of the Barclays Center in Brooklyn for a show he called "Contemporary Color," which is now a promising documentary of the same name.

If you're not familiar with color guard, you're not alone: Byrne told the New York Times he estimated it was "completely unknown to 98 percent of New Yorkers." For the uninitiated, color guard is a form of beautifully melodramatic flag-waving, saber-tossing choreography. (Virginia's McLean High School has a helpful introduction in the form of its color-guard recruitment video.)

While a Times review of the "Contemporary Color" live show was mixed, the documentary's ability to examine the interior lives of the performers, the history of color guard and the jubilation backstage promises an entirely more revealing, and resonant, portrait.
