Earl Scruggs was a innovative instrumentalist who helped to define American music in the 20th century, and as a result influenced every banjo player who came afterwards.

As a tribute to the recently-passed banjo genius Earl Scruggs, here is a feature-length documentary about him from the early 1970s. You’ll recognize none other than Bob Dylan in the opening; check out the grin on his face as they launch into a tune together.
