The Houston-born singer/songwriter Rodney Crowell talks about growing up on the rough side of town with the ghost of Hank Williams as a “family member,” as well writing songs for his recent duet partner Emmylou Harris. He also wrote for many of the country heavy weights from Jerry Reed to Guy Clark and Bob Seeger, and was also the antagonist in Rosanne Cash’s signature tune “Seven Year Ache.” Then we’ll sit down live in a rare visit to Nashville (!) with the Crescent City’s Nite Tripper himself Dr. John, who reminisces about and demonstrates his early days at the piano, and on a music industry, “spying mission” that could only happen in New Orleans.

This week on American Routes we cue the music and dim the lights for great music moments in film. We’ll sit down with Oscar nominees Joel and Ethan Coen, writers/directors of such iconic films as True Grit, O Brother Where Art Thou? and The Big Lebowski and discover the magical role of music in their movies. Then, conversation with cinema-verite masters D. A. Pennebaker and Chris Hegedus, who’ll detail the craft of their “glorified home movies” such as Dylan’s Dont Look Back and The War Room, and their latest feature Kings of Pastry. Plus, clips from films we love, and songs that make the silver screen shimmer.

What’s in a name? Listen in and you’ll find out why Emmett Ellis Jr. became the bluesman Bobby Rush; how folks get names like Topsy (Chapman), and Sherman & Wendell (Holmes); and how country singer George Jones became known as “the possum.” Also, we talk to Yale anthropologist David Watts about names of non-human primates.
