Power/Thrash/Speed Metal from Sao Paulo, Brazil. The idea of this band started long ago ... since three guys from jandira decided that they'd make some noise. Influenced by American Thash metal bands, German Metal, NWOBHM, Hardcore and lots of other stuff, the band started building it's own style. In May 2001, Leo Axekiller (bass /vocals), Marcelo Barbosa (guitar /vocals) and Bruno Barbosa (drums), create in the spine of Jandira Jackhammer, previously known as Wild hunter. By that time Ivan was part of the band as a bass guitar player.
