Os Mutantes aren’t just a band—they’re a cultural phenomenon. Born in the explosive Tropicália movement of late-60s Brazil, they flipped the script on what Brazilian music could be, fusing it with fuzzed-out psychedelia, absurdist humor, and radical sonic play. Their sound was revolutionary then, and still feels otherworldly now. Few groups have so boldly redefined the limits of pop music. Their fearless experimentation and surrealist spirit reshaped Brazilian culture—and continue to ripple across global music scenes, from avant-rock to experimental pop.
