Star Trek meets Buena Vista Social Club in this psychedelic western musical as Welsh pop legend Gruff Rhys (Super Furry Animals) takes us on a pan continental road trip in search of his long lost Patagonian uncle, the poncho wearing guitarist Rene Griffiths. In 1880, following a controversial horse race that led to an unresolved death, Gruff Rhys' family split as Dafydd Jones took his young family to join the burgeoning Welsh community in Patagonia, South America. There was to be no contact between the families for almost a century when in 1974 Rene Griffiths arrived in Wales with his Latin infused Welsh love songs and became an overnight sensation. Director Dylan Goch follows Gruff Rhys on a tour that takes in the theatres, nightclubs and desert teahouses of Wales, Brazil and the Argentine Andes as he discovers what became of his family, the Welsh Diaspora and its musical legacy. Gruff Rhys' latest film project, I Grombil Cyfandir Pell: American Interior, will be shown on S4C in September.
