The best metal scene in sudamerica is the Chilean scene!... Coprofago (Jazz Death Metal, the best chilean band ever), Dorso (Gore old school death metal), Dogma (Like Metallica but more more thrashers), Criminal (The most famous chilean band, thrashers), Totten Korps (brutal death, amazing voice), Burning Dusk (melodic death metal), Defacing (Amazing Death/Grind), Sheolgeena (death blast), Mar De Grises (doom), Poema Arcanus (doom), Psicosis (thrash), Torturer (death/thrash), Sadism (great brutal death metal)etc etc etc...
