Rose Royce "I Wanna Get Next To You" (1976)

"Car Wash" is a vastly underrated film. The structure is like a Greek tragedy, where all of the action takes place in 24 hours. Within that structure is a dizzying cast of characters, all perfectly resolved with their independent and intersecting life dramas. Most of them experience an arc where their situations at the end of the film are very different than at the start. And it all takes place with Los Angeles as the backdrop, another important element as the story couldn't have taken place anywhere else.
