In 1792, John Evans, a farmhand from Snowdonia travelled to America to discover whether there was a Welsh-speaking Native American tribe walking the Great Plains. Over 200 years later, distant relative Gruff Rhys (Super Furry Animals) retraces the explorer's route through the continent by means of an investigative concert tour. A unique project that blurs the boundaries of music, literature and film and investigates what really happened in the heart of the new world.
