At approximately the same time as the rise of Nueva Trova, similar musical genres across the world were increasing in popularity as part of a roots revival; these involved the popularization of traditional music welded with socio-political lyrics. Nueva Trova was most closely influenced by South American (especially Chilean) nueva canción, Spanish Nova Cançó, Bolivian canto nuevo, Portuguese canto livre and nova canção, and Brazilian Tropicalismo. At about the same time, Puerto Ricans like Roy Brown, Andrés Jiménez, Antonio Cabán Vale and the group Haciendo Punto en Otro Son also became popular.
