Case 63 Spotify

Podcast dramas are still rare compared to the endless true crime, earnest opining and sub-comedy babbling that comprises so much of the platform. Here, US stars Julianne Moore and Oscar Isaac join forces in an intense, tightly written (by Chilean author Julio Rojas) double-hander set around a New York psychiatrist’s sessions with a man claiming he has timetravelled back from the future to save the world. An adaptation of Spotify’s most listened to podcast in Latin America, it is instantly addictive and, served up in episodes ranging from six to 13 minutes, eminently bingeable.

Composer of the Week: The Harlem Renaissance Radio 3, noon

Concluding a week of hugely enjoyable editions on the pioneering music of the Harlem Renaissance – a nod to the ongoing EFG London Jazz Festival – Donald Macleod turns his attention to a jazz giant. Arriving as an unknown in New York in 1924, Louis Armstrong was a charismatic personality and his trumpeting genius soon made him stand out from the crowd – evident here in early recordings of Sugar Foot Stomp and Naughty Man with Fletcher Henderson’s band, as well as later post-fame highs such as Laughin’ Louie and, of course, When the Saints Go Marching In.
