Indigo and Naugahyde

Lots of people have written in wanting to know more about these salt traders. The band is Tinariwen. They are Tauregs, once known as the "Blue Men of the Desert" because their indigo dyed headscarves left their faces blue. Here's more of their music:

More Tinariwen videos can be seen on this youtube page, check African playlist for a batch of them.
Meanwhile, folks also wanted to know who these girls are, dancing on stage with the salt traders in the swamp.
The young women are Newcomb College art history majors who snuck into the swamp a year ago, hoping to discover a genuine primitive folk artist...instead, they stumbled straight into the camp of Ernie K Doe and the Undead Soul Singers. Those girls have been here ever since.
The older lady dancing in blue is the Queen of the Bayougoula Indian tribe...some say she's 700 years old, but I don't believe it. She's 900 if she's a day. She sure can dance, though. I like to listen to her tell of the days when Cabeza de Vaca and his crew came walking through these parts. The remnants of the Bayougoula have made their last stand here in the swamp, pretty much like the rest of us.
