Sun Ra claimed to be an extraterrestrial being from Saturn who could teleport you to other planets with his music. That may or may not have been true, but he certainly was the leader of one of the most influential jazz ensembles of the 20th century, and he’s often called the father of Afrofuturism. I talk with artist Cauleen Smith and writer John Corbett about Sun Ra’s creative journey, and why he was light years ahead of his time. The musician Idris Ackamoor explains why Sun Ra was an inspiration for his band The Pyramids. And Ytasha Womack, author of fiction and non-fiction books about Afrofuturism, discusses why imagining the future is still a radical act.
