A trailer from the upcoming documentary on psychedelic rock pioneers "Os Mutantes".

The story of Os Mutantes is perhaps one of the strangest in the entire history of rock music, and has served as heady inspiration for artists as varied as David Byrne, Beck, Sean Lennon, and Nirvana. Imagine a 1960's Brazilian rock band on a weekly television program disguised as aliens, witches, or conquist-adors performing surreal hymns to such bizarre figures as Don Quixote (or at other times: Genghis Khan and Lucifer) while tossing massive nets and giant rubber caterpillars across their audience. Add the fact that they had the courage to perform a fusion of traditional Brazilian rhythms with psychedelia at a time when the "MPB" (the Brazilian music establishment) were openly hostile to the wild sounds of American rock 'n roll and this provoked even further outrage by fashioning their own outrageous musical instruments, often constructed out of such common household objects as rubber hoses, cans of hot chocolate, or bottles of bug spray. Finally, they did all of this under the watchful eyes of a brutally repressive right-wing military dictatorship, as they were regularly censored by the government while performing alongside such musical revolutionaries as Gilberto Gil and Caetano Veloso (who, like many artists in Brazil at the time, were imprisoned and exiled for their political stance).
