Doug Kershaw is the most famous Cajun musician in history. His brother, Rusty, is not, though you may be more familiar with his work than you realize. 

These brothers come from a long tradition of surviving against the odds, against a world that would just as soon see you dead as see you succeed. Starting from nothing but a houseboat in Louisiana, they fought their way through an unscrupulous industry, through honky tonk stages screened off with chicken wire, onto the biggest stages in the business, in order to create some of the greatest music ever made. Then, they battled themselves, their past and their addictions.

Side note: what the hell is "Cajun"? Swamp stuff, right? Well, let's talk about all of that.

This episode is recommend for fans of: Hardcore History, Neil Young, Johnny Cash, Bob Dylan and discovering unbelievably good music that you've never heard.
