On its face, this is a short documentary presented by Clark County about a mural commissioned by Clark County, so there’s a promotional feel to this. However, the documentary — which, like the mural project, is called Unsung — is essentially a history lesson. The mural in question is spread out over 21 pillars at the Pearson Community Center. Each of those 21 pillars tells the timeline highlights of the Historic Westside. The title Unsung comes from the under-celebrated legacy-building of the people and institutions which would build and lift the Westside, most of them people from the Black community who lived there. Locals Gwendolyn K. Walker and Zachary Fried made the film, which centers the work of artist Mike Norice, who created the artwork, and Claytee White, the UNLV historian who guided the selection of representations on the pillars.
