Coprófago (from greek, copro: shit, fago: eat) was formed in June of 1993 in Santiago, Chile by Sebastián Vergara (guitar, vocals), Pablo Álvarez (guitar) and two friends of theirs. In November of 1994 they recorded their first demo, a 4 songs tape featuring probably the youngest kids in metal scene (their average age was about 15 at the release time). Although the demo didn't have a good reception from the press, that tape is now sold out. In March of 1995, Marcelo entered as the definitive drummer. With this line-up they played during 1995 and 1996.
