For all those stuck at home or stressed out during these uncertain times, here’s an hour of uplifting music from Mali, Cuba and South Africa. Vusi Mahlasela, Alex Cuba, Afel Bocoum and Oumou Sangare have all known the travails of personal pain and political turmoil. And yet all find the strength and vision to create music that soothes and reassures even as it moves dancing feet. On this program, we hear fresh music and words from all four. Produced by Banning Eyre and Sean Barlow.
