Icon, Legend, Musical Genius; words to describe Cassio Audi. Cassio Audi brought the heavy metal scene to life when he performed as a drummer and singer in the 1980’s and showed his raw talent. He played in the band Viper with four talented members, all teenagers at the time, and released their first demo album called The Killer Sword in 1985. Tracks included on this album were Signs of the Night and Nightmare. Their first album was released in 1987 called Soldiers of Sunrise that included tracks Knights of Destruction and Soldiers of Sunrise. Soldiers of Sunrise sold more than ten thousand copies and was one of the greatest hits in the music industry in Brazil. Along with the release in Brazil, the album was also released in Asia, Europe, and USA. Other popular songs were Knights of Destruction, Wings of Evil, and Killera, all released in 1987. Audi spent his time composing and arranging the songs for the band. The dedication that he had was unreal that many people don’t realize until in-depth research unleashes it all. The entire band focused on improving their talent far and above what fans expected. Audi and the group were inspired by Iron Maiden and other British heavy metal bands. Audi, however, inspired other musicians in the rock world due to his extreme and insane power on the drums. Although the band was considered pop/rock genre, a more appropriate sound would be power metal, thrash metal, and alternative rock. Audi is from Brazil but his name is recognized all around the world. His music was so massive that Viper became iconic in the heavy metal band industry and played shows in Europe and America. Fans could see the Audi’s and the band’s talent and that they had a great future. In 1989, Audi left the band even though the second album was extremely successful.
