In the past year and a half, pedal steel guitarist Robert Randolph has spent over $5,000 on iTunes. "Before this record, I didn't sift through music past the seventies," says Randolph. So he's been catching up. Guided by the legendary T Bone Burnett, Randolph mined the canon of 20th century African-American music, pulling from gospel, blues, rock and field recordings from as far back as the '20s to find inspiration for his new album, We Walk This Road, which comes out on June 22. "T Bone is a link between the past and the present," notes Randolph. "He listens to music our grandmothers would listen to as children - the music people working in the fields across the south likely sang nearly a century ago. These are the real roots of rock and roll, where everything comes from.
