Emerging during the transformative late 1960s in Brazil, amidst political upheaval and the rise of psychedelic tunes, Os Mutantes played a pivotal role in the tropicália movement. Blending fierce guitar sounds with traditional Brazilian beats and a forward-looking soulful essence, their melodies often drew parallels with the Beatles. Icons such as Beck, Flea, and David Byrne count them as influences. They showcased their enduring spark in their debut at the Ford.
