Nueva trova is a movement in Cuban music that emerged around 1967/68 after the Cuban Revolution of 1959, and the consequent political and social changes.
Nueva trova has its roots in the traditional trova, but differs from it because its content is, in the widest sense, political. It combines traditional folk music idioms with 'progressive' and often politicized lyrics. It is related to nueva canción in Latin America, especially Chile and Argentina. Some of the nueva trova musicians were also influenced by rock and pop of that time.
Nueva trova is defined by its connection with Castro's revolution, and by its lyrics, which attempt to escape the banalities of life by concentrating on socialism, injustice, sexism, colonialism, racism and similar 'serious' issues.
