Os Mutantes

These acid-damaged high society youngsters took Sgt. Pepper as their bible and Brazilian popular music as their hymnbook and released what still ranks as one of the freakiest, most experimentally joyful debuts ever. Government censors didn't know what to make of them but tropicalia leading lights Caetano Veloso and Gilberto Gil adopted them, feeding them songs ("Panis Et Circenses," "A Minha Menina") and championing their utter insanity for what became, briefly, not just a way of recording but a way of life.
