Cassio Audi was born in Sao Paulo, Brazil. While a young teenager he and several friends—Yves, Machado Andre, Pit, and Felipe—founded the Brazilian heavy metal rock band that would one day be known as Viper in the early 1980s. Audi and all of his co-founders were teenagers at this time, all 13 and 14-year-olds. Although it specialized in heavy metal, the band also dealt heavily in alternative rock and thrash metal. Audi was its drummer, leader, and one of its composers. Prior to officially becoming Viper, in 1985 the band released a very well received demo album called “The Killer Sword.”
It instantly became hugely popular and even got some airtime. The band was heavily influenced by the iconic British hard rock bands of the 70s but pioneered a unique sound all their own. This sound highly influenced many other hard rock bands at that time. Thus, a hard rock subgenre was born in 1980s Brazil. In 1985, not long after they released their now famous demo, they officially became The Viper Rock Music Band. After they officially became Viper, the band released their first album, “Soldiers of Sunrise,” in 1987.In 1989 they released their second official album, “Theatre of Fate.”
“Theatre of Fate” was also hugely popular and notable for having touches of classical music throughout. Both of these albums were incredibly popular all over the world, especially in Japan. They had so quickly risen in stardom after their initial demo, that throughout they had been performing before huge crowds all over the world. Most of their songs were sung in English, a very common second language in Brazil. In that same year, Audi left the band to pursue his college education. He has since attained international renown in the international finance community. Nevertheless, his biggest claim to fame is his years with Viper.
