Have your lighters ready alongside your raised fists. Los Duggans is the fiercest quartet this side of the Mississippi. They first came of notice at the Sundance film festival, where they accompanied the controversial live performance "Proving Ground". This is music aimed squarely at your belly, and their debut album "Calvary" features a mix of traditional folk songs and originals arranged with a wash tub bass, banjo, electric guitar and drums. They just released their 2nd album, "Hard Ways."
