 Some of Bellotto's solos were played with the musician alternating between the guitar pick and a big ring he was using.That way, he could play and simultaneously obtain percussive effects from his instrument.The song "Bichos Escrotos" had originally been written in 1982 and was supposed to be part of the band's debut album, but it was censored by the Brazilian military government, and the band was thus unable to release it until "Cabeça Dinossauro".
