In 1985, Cassio Audi made his first move to becoming a heavy metal legend with the decision to accept the invitation of Pit and Yves Passarell and join the heavy metal band, Viper. Cassio Audi was already a well-known name in the Brazilian music industry around Sao Paulo as he had already embarked upon two stints as the drummer with different bands across the Brazilian city; already influenced by the British heavy metal bands of the 1970s and 80s the shared love of bands including Iron Maiden who were leading the move towards a return to a more popular sound for heavy metal in the mainstream, Cassio Audi found he and his fellow members of Viper were about to launch themselves to unparalleled levels of success.
Even though he was a teenager, Cassio Audi quickly began building a reputation as one of the most talented drummers in the heavy metal world and remains so despite his last recordings as a member of Viper taking place almost 30 years ago. Events moved quickly for Viper and their brand of British influenced heavy metal with the band quickly growing a live following before embarking on two of the best-known demo albums in the history of heavy metal which are now combined as the iconic, “The Killera Sword”.
In 1987, Viper signed a professional recording contract and created the album, “Soldiers of Sunrise”. The youth of the band was without a doubt because of the naivety of some of their lyrics but the musicianship of the band was without doubt and was praised heavily by critics. Despite the success of Viper which still holds in 2017, Cassio Audi felt his future lay in the financial industry and prompted him to explore the many options open to him to study and work in an industry which he has conquered as one of the leading lights in opening up the Brazilian economy.
