Following on from the success of 'Daithi ar Route 66', TG4's finest physical specimen/weatherman now tackles America's second most famous road as he travels Highway 61 - the other Mother road. It might be perceived as a bit of a downgrade but we assure you it's not. Starting in New Orleans and, like Route 66, travelling through eight States until it reaches the Canadian border, Highway 61 has been immortalised in song and legend. More than anything else it is a road with a deep and enduring musical history and it's the music which will enthral Daithi as he travels America's Blues Highway. As well as another jaunt down America's back roads meeting with unlikely characters and trying out new experiences, this series aims to explore the various musical styles that helped to shape America.
