It's a story you could write a song about. It's sometime in the 1960s or '70s. A teenager in Tokyo slips a borrowed cassette into a player and is transfixed by what he hears: the sound of guitars, banjos and mandolins; the call of mountains far, far away. He saves his money and flies to the United States, gets on a Greyhound bus and makes a pilgrimage to legendary folk festivals. He hears bluegrass music live for the first time and it changes the course of his musical life.
