NOISE
One of the best bands of Brasilian noisecore scene. Been playing for at least dozen of years and remained 100% underground and uncommercial. Most of the recordings are only available from the band, and not for sale. Even the records such as "Edge of Painful Sensation" comp. LP where Noise was involves, was pressed c. 200 copies and included statement that it should not be sold for money. Only obtained via trades. 3 member line-up produces dirty rehearsal sounding, yet well audible noisecore with very fast drums and aggressive vocals. I would assume band is still alive since there is some Noise recordings being released during this year.
