This documentary mixes performances, interviews and reenactments to celebrate the Funk Brothers, the 1960s soul hitmakers. As the musicians behind the Temptations, the Four Tops and others, the ''brothers'' were hugely successful, yet relatively anonymous compared to the famous singers they backed. They get their due here, as Richard ''Pistol'' Allen, Benny ''Papa Zita'' Benjamin and bandmates discuss their Detroit youth, studio sessions alongside Marvin Gaye and nonstop touring.
