Andrea Díaz Cardona, the director and producer of the BBC Mundo documentary El extraordinario viaje de Carlos y Alvin, tells the story of Carlos and Alvin, who, despite being born in different countries, by luck met and discovered that they had parallel lives: they were both premature babies and became blind as the result of the same medical error. Both were self-taught musicians, live alone in Canada and are refugees with restrictions on visiting their own countries, despite which they decided to visit the country of the other. Díaz Cardona will talk to José Carlos Cueto, also a BBC Mundo journalist.
