For Harper the disc was the chance to work with one of his personal icons - the 43 year old guitarist has long had a great respect for American blues and folk music, and he will make clear why he loves Musselwhite so much, both for his blues harmonica talents and his ability to move beyond color lines. Plus Billy Bragg. The Englishman recently released Tooth & Nail, his first new disc in five years. He shares how delving into the Woodie Guthrie archives in the late 90s with Wilco still has an impact on his work today, and why he shouldn’t just be seen as a political songwriter.
