Walter Giardino started in V8, but his style soon clashed with that band and left it (he did not take part in any V8 LP). He was joined by Gustavo Rowek, the drummer of V8 that also left the band, and a pair of session musicians. Those two were soon replaced by stable members, Saul Blanch, Guillermo Sanchez and Sergio Berdichevsky.
The first LP was a success, but the second one (with the new singer, Adrian Barilari) gave them a success greater than any heavy metal bands in the country, even playing regularly in TV programs. They were the first metal band to play in a stadium. The LP "El Libro Oculto" was disliked by Barilari, who left the band. He was replaced by Mario Ian, the singer of Kamikaze, and later by Gabriel Marian. After a couple of CDs with low sales, the band broke up.
The band reunited a few years later, back with Barilari.
