New Sounds returns to Ireland for the fourth part of our series on the country's contemporary music scene. For Part 4, in the 7-part series, host John Schaefer speaks with Derry-based composer Neil Burns whose work bridges atmospheric pop and contemporary classical music. Burns discusses his piece "Walls of Sound," a kind of audio tour of Derry, Ireland's city walls that includes processed environmental recordings and spare accompaniment. Neil Burns also shares how his atmospheric pop work has informed his approach to his contemporary classical composition. Later in the hour, John Schaefer meets with Greg Caffrey in Belfast to discuss making music through tough times in Belfast and the Hard Rain Soloist Ensemble he founded.
