Before he became a prominent person in the field of finance, Cassio Audi was also a professional musician. He is the founding member of a rock band known as Viper. Together with his four friends, Felipe Machado, Yves Passarel, and Andre Machado, they started the Viper band in 1985. According to Cassio Audi, their source of inspiration was from heavy metal music, specifically the Iron Maiden. Cassio Audi was good with instruments and his role in the band was to play drums. With his expertise in drums, Cassio and his bandmates managed to transverse the world of music. This was witnessed by their first demo album known as the Killer Sword. The album consists of tracks such as Killera, Princess from Hell, and Nightmare.
Cassio Audi and his team released their first album in 1987 known as the Soldiers of Sunrise. In the album, Audi was playing the drums. The album also included some tracks from the demo album. However, the music was criticized by some fans stating that the skills possessed by the group required some tuning and refinement. According to Allmusic, the Soldiers of Sunrise was rated four-star, and it has been released and redone several times since its first debut. Unfortunately, Cassio Audi left Viper rock band in 1989 when the group was on the verge of releasing their second album, Theatre of Fate. Unlike Soldiers of Sunrise, the album gained popularity across America and Europe. It was a successful album because fans of the heavy metal music praised the members of the Viper Rock Band for their high-level talents and skills.
When he left the music career, Cassio Audi joined the University to pursue Degree in Business Administration. He also attended Sao Paulo University, from where he received his MBA in Finance. Through his studies and financial career, Cassio managed to acquire several skills in the industry of financial management and real estate.
