During the 1970s, Brazilian luminaires Sá, Rodrix & Guarabyra invented what they called “rural rock” as a mixture of anglophone folk rock and música caipira (an umbrella term for the Iberian-descending, acoustic-guitar-based musics from the countryside of Brazil). In 1974, Rodrix dropped the band and Sá & Guarabyra continued as a duo, detaching themselves even further from conventional MPB and going simultaneously more regional, towards genres like sertanejo de raiz and xote, and more pop, towards the esoteric country ballads of Van Morrison or JJ Cale.
