João Aguardela was one of the most distinctive characters in contemporary Portuguese music. Over more than two decades, he blended tradition and experimentation in projects such as Sitiados, Megafone, Linha da Frente and A Naifa, always seeking new ways to create. Through archive footage, personal films, concert recordings and interviews with family and friends, Esta Vida de Marinheiro traces Aguardela’s journey through music and the people who were part of his life.
