When Soul Train was first nationally syndicated in October 1971, there was nothing else like it on TV. It became an iconic Black music and dance show — a party every weekend that anyone could join from their living room. In the first episode of a three-part series exploring crossover in pop music, we break down the lasting influence of Soul Train on our culture with Hanif Abdurraqib, author of A Little Devil in America. We ask: Why has there never been another show like Soul Train since it went off the air? You can follow us on Twitter @NPRItsBeenAMin and email us at samsanders@npr.org.
