While much of the Brazilian pop-music scene was caught up in the groundbreaking fusion of traditional folk stylings with Rock and Roll, Baden Powell was lingering further in the past. Tropicalia was taking the underground by storm; applying fuzz guitar, jazzed out sensibility, and tongue-in-cheek humor to far more danceable and groove-oriented cuts than the Anglo-American scene could comprehend. But prior to Os Mutantes massive breakthrough, Powell was working through his own vision of Brazil’s emergence into the mainstream. In 1966, Tristeza on Guitar was released as an essential first step on the road to full-blown Tropicalia.
