 While nueva canción in other countries primarily functioned in opposition to existing regimes, nueva trova emerged after the Cuban Revolution and enjoyed various degrees of state support throughout the late twentieth century.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 that concentrate on socialism, injustice, sexism, colonialism, racism and similar 'serious' issues.
