Critically acclaimed music show American Routes, hosted by Nick Spitzer, is a weekly two-hour public radio program produced in New Orleans, presenting a broad range of American music — blues and jazz, gospel and soul, old-time country and rockabilly, Cajun and zydeco, Tejano and Latin, roots rock and pop, avant-garde and classical. Now in the 20th year on the air, American Routes explores the shared musical and cultural threads in these American styles and genres of music — and how they are distinguished.
