“Following a US-backed military coup in 1964, many young artists in Brazil – disillusioned with the apolitical nature of bossa nova – searched for a music that would speak to their contemporary world,” (UDiscoverMusic). “By the late 60s, a group would answer the call through a movement known as Tropicália. These artists – chiefly Caetano Veloso, Gilberto Gil, Os Mutantes, and Gal Costa – sought a ‘universal sound’; a merger of local and international styles that was both cosmopolitan and distinctly Brazilian. Their fusions of bossa nova, psychedelia, and rock ’n’ roll remain totally unique.
Costa began her career as a bossa nova singer before joining the ‘tropicalists’ in 1968 … Atop soaring string arrangements, Costa’s voice holds a powerful tenderness. Depending on one’s interpretation, it’s either unashamedly sentimental and detached from its political context, or an intentionally saccharine, ironic rebuke to consumerist society. Veloso’s lyrics are typically oblique, allowing for either reading to make sense … If there was one guiding principle of the Tropicália movement, it was the freedom to be many things at once. Their music was both popular and avant-garde, politically principled but undogmatic, distinctly Brazilian but syncretic, lyrically piercing but ambiguous.”
After a sunny start in B major, “Esquadros” (Squares), released in 1999, shifts to the parallel B minor from 1:11 – 1:23, bolstered by beefier groove, before returning to the original key. The key alternates many more times throughout, but the increasingly unsettled, unresolved instrumental outro (starting at 3:20) erases any memory of the tune’s major key sections!
