All Bob Dylan Pictures

Bob Dylan performs as the kick-off act of the Pawtucket Arts Festival at McCoy Stadium, in this Thursday, Aug. 24, 2006 file photo, in Pawtucket, R.I. As teenagers in northern Minnesota in the late 1950s, Ric Kangas and Bobby Zimmerman would spend hours playing guitar and singing. During one of those sessions, Zimmerman asked his friend to record it.Kangas had no idea he was recording the man who would soon become Bob Dylan. Years later, he came across the tape, which features Dylan singing three songs and playing guitar on another.
