Anybody familiar with this weird '80s Brazilian hardcore/thrash/death metal band? I highly recommend their album 'Toxin Diffusion.' Raw and aggressive with interesting song structures, and an underlying sense of humor despite the harsh vocals (typical of Brazilian thrash, easier on the ears than Chakal, though). Fans of Mutilator or early Sepultura should check 'em out.

The name rings a bell. My brother had a pen pal in Brazil back in the late 80s and they used to trade vinyl LPs back and forth (a very expensive hobby back then!), and I believe my bro got the "Toxin Diffusion" album from him. (I also remember him getting an album by Mutilator, the other band you mentioned.) Can't recall what they sounded like tho.
