The musical offering of singer and cultural agitator Álvaro Romero and producer and musician Pedro Da Linha expresses a relationship between two cultures - the Portuguese and the Spanish - that are as different as they are related, combined with echoes of their relationship with the Atlantic areas of America and Africa. Electronica and flamenco act as starting points for an investigation into the directions, currents and shifts in the music of both countries, with an emphasis on the way colonization has marked the music of past and present.
