Cassio Audi had a relatively quick but overall successful and impactful musical career. Hailing from Sao Paulo, Brazil, he began drumming with his first band Viper, in 1985 while still a teenager. Along with Audi, Viper’s founding line-up featured Andre Matos as lead vocals and keyboard, Pit Passarell on bass, Felipe Machado and Yves Passarell on guitar. Viper played music from multiple genres, including but not limited to thrash metal, heavy metal, power metal and alternative rock. They reference British metal and Iron Maiden as their strongest influences.
Viper’s first demo album was “The Killera Sword”, which they recorded in 1985. The 24 minute 13 second-long record featured six independently recorded tracks, with three of the most popular ones including “Signs of the Night”, “Nightmare”, and “Killera Princess from Hell”. The album cover featured an early rendering of Viper’s logo and a photograph of the teenage hair rockers in casual poses.
Two years later in 1987, Viper released their first official studio album, called “Soldiers of Sunrise”. Some highlight tracks from that album include “Signs of the Night”, “Knights of Destruction”, “Nightmares”, and “Soldiers of Sunrise“. This album gained lots of buzz in the Brazilian metal scene and made a splash internationally by being featured in the Metal magazines Kerrang, Metal Fores and Metal Hammer. The album also helped cement Audi as a household name in the realm of skilled Brazilian drummers. “Soldiers of Sunrise” went on to sell over ten thousand records.
After “Soldiers of Surnrise”, Viper released “Theatre of Fate” in 1989 internationally in Europe, Asia and the US. What stood out for this album was its mixing of metal with classical genres. For example, the albums final track “Moonlight” is based off of Beethoven’s “Moonlight Sonata. The album had some major hits and even outcharted world-renowned rock groups like Nirvana and Van Halen in Japan. It also included what will likely go down as the fan favorite Viper track of all-time – “Living for the Night.”
Although Cassio Audi did not participate in the recording of this album, he continued to tour with Viper. Ultimately, in 1989 he left Viper and pursued a different career path. However, his impact on the Brazilian metal scene continues to this day.
