Sergio Mendes and Brasil 66‘s “smash formula,” according to AllMusic, was “cover versions of pop/rock hits backed by lavish strings, a simplified bossa nova rhythm, and the leader’s piano comping.” The group’s covers of the Beatles’ “Fool on the Hill” and Simon and Garfunkel’s “Scarborough Fair” reached #6 and #16 on the US pop charts, respectively. “Even though he had become thoroughly embedded in the consciousness of mainstream America, Mendes still managed to have it three ways: exposing first-class tunes from little-known Brazilian talent, garnering commercial hits, and also making some fine records.”
The San Diego Union Tribune quotes Mendes speaking about his introduction to the USA: “… the idea was to bring a band from Brazil that represented what Brazilian music is — the vitality, the romance, the rhythms, the sensuality. I was not thinking to put a label on it, but to bring Brazilian music to the world.”
The energetic “Lapinha” (1968) alternates between D major and D minor until the groove drops out for a huge shift to Eb major late in the game (2:27).
