Touring North America in support of their first studio album in over 30 years, Os Mutantes were one of the most influential psychedelic rock / tropicalia bands to come out of Brazil in the late 1960’s and early 1970’s. They’ve influenced artists from Beck to Kurt Cobain to David Byrne. And while the current lineup is filled with a few younger faces, the heart of original lineups, guitarist and singer Sergio Dias and drummer Dinho Leme, are intact (minus the vocals of one Rita Lee).
Here’s an old, old, old compilation of some early Os Mutantes stuff from youtube:
