Soul America (BBC4, 9.30pm)

MEMORIES of the late 1960s and early 70s, a period when inequality, poverty and racism fanned the flames of radical black politics and resulted in a harder soul sound. Stax Records went from being a label built around an integrated house band to becoming a black-centric business spearheaded by Isaac Hayes’s expansive, flamboyant soul symphonies. Meanwhile, the Temptations tackled socially aware subjects such as the Detroit riot and absent fathers, while Marvin Gaye conceived the epic What’s Going On. Narrated by Carleen Anderson.
