Os Mutantes didn’t just ride Brazil’s Tropicália wave—they rewired its circuits with psychedelic voltage and studio trickery that still sounds ahead of its time. Formed by Sérgio Dias, Arnaldo Baptista, and Rita Lee, this São Paulo trio spliced fuzz-drenched rock with samba, satire, and surrealism—turning every song into a kaleidoscopic trip that left critics scrambling for adjectives. While the lineup evolved over decades, Sérgio Dias has remained the band’s guiding mutant, fusing old magic with new alchemy. Their 2023 album Zzyzx—released by Think Like A Key Music—isn’t just a return, it’s a reinvention: packed with never-before-heard originals and cosmic mischief that feels both vintage and uncharted. This is Os Mutantes as time travelers, not time capsules—still mutating, still magnificent, and still proving that in Brazilian rock, revolution and evolution are one and the same.
