Why did the Brazilian left wing tend to criticize international styles of music such as rock 'n' roll? They feared that rock 'n' roll in Brasil would lose its original qualities and become diluted by Brazilian influence. They reacted negatively to the open displays of sexuality by rock artists such as Elvis Presley and The Beatles. They disliked its lack of Afro-diasporic sonic qualities, which they considered central to Brazilian musical patrimony. They considered it a form of cultural imperialism and associated it with Brazil's right-wing dictatorship. None of the above.
