In this season of the GroundTruth podcast, called “The New American Songbook,” we ask how immigration continues to define our musical culture, and crucially: how music can help us understand the lives of today’s immigrants. Essential funding for this project was provided by Mass Humanities and WGBH News. Additional funding was provided by the John D. and Catherine T. MacArthur Foundation. You can hear the podcast in the chapters of this project, or on Apple Podcasts, Stitcher, RadioPublic, SoundCloud and other podcasting apps.
