VIPER was formed in 1985 by Andre Matos (vocals), brothers Pit Passarell (bass) and Yves Passarell (guitar), Felipe Machado (guitar), and Cassio Audi (drums). The first show was at the traditional Lira Paulistana theater, in São Paulo, on April 8th.

At the time, the musicians were still teenagers. The band then started to perform on the local circuit and recorded a demo “The Killera Sword”, which was well accepted by the fans after being released on a popular radio show.

They were invited by the independent label created by Rock Brigade magazine to record their first album, “Soldiers of Sunrise”, released in 1987. The album was praised by the specialized press, and the band was invited to perform the opening show for Motörhead in São Paulo, for more than ten thousand people.
