Singer-songwriter Dom Flemons’ newest album, Black Cowboys, takes a rarely seen look into a nearly lost piece American history. Its 18 tracks are a mix of originals, traditional folk tunes, and many seldom-heard songs that chronicle the role played by African-Americans in settling the West after emancipation in the 19th century. Flemons’ is a fifth-generation Arizonan and a former Flagstaff resident, and tomorrow he returns as one of the headliners at Pickin’ in the Pines. For the latest installment of KNAU’s series Eats and Beats, I had a chance to talk with Flemons about the very personal genesis of Black Cowboys.
