The story of seminal guitarist and singer Bert Jansch, from his early days in Edinburgh, Scotland, to becoming the acoustic guitarist that everyone wanted to be. As a teenager, in the early 1960's Bert sat at the feet of Brownie McGhee at the Howff Folk Club in Edinburgh mesmerised by 'Key to the Highway'. Armed with that raw American Blues influence and a bewildering technique, he fashioned sublime interpretations of traditional and blues music on the acoustic guitar.
