Lucy Duran travels to rural north-east Brazil in search of traditional Forro, a style of country music much-loved there but little-known outside. She reaches the Sertao - Brazil's vast, hot and, in parts, lawless semi-desert. She meets a community of former slaves who settled in this remote part of the country to escape their Portuguese masters. Including music for the indigenous pifano flute and a session by local politician-cum-protest singer Sebastian Dias.
