oprofago (from greek, copro: shit, fago: eat) was formed in June of 1993 in Santiago, Chile, by Sebastián Vergara (guitar/vocals), Pablo Alvarez (guitar) and two friends of theirs. In November of 1994 they recorded their first demo, a 4 song tape titled simply Demo 1, featuring members whose average age was about 15 at the release time. Although the demo didn't have a good reception from the press, the tape sold out. In March of 1995, Marcelo Ruiz then entered as the drummer to replace original drummer Ignacio Suit.
In 1997 they recorded their second album, Images Of Despair. Before finishing the recording, the bassist left due to musical differences. Felipe Castro, old friend of Pablo and Sebastián, took his place and finished the recording. The music of the LP was faster than any previous material, but some progressive elements were present, due to Pablo´s growing interest in Jazz-fusion at that time. But the album wasn't released right away due to a desire to augment Sebastián's low growls, but they failed to find a suitable vocalist.
In December of 1998 the promo single Empty Creature was released, featuring Pablo's first attempt on vocal duties. The previous full length would finally come out in September of the following year with Pablo as a definitive singer, making of Coprofago a 2-frontmen band; the album received a favorable critical response. Empty Creature was included in Grinder magazine's compilation, and the whole album had some airplay in local Metal radio shows even one year after its debut.
Soon after I.O.D.'s release, Felipe left the band, with Rodrigo Casto as his replacement. Rodrigo is a fretless player, something uncommon in Metal music, so his inclusion in the band reinforced the singularity of Coprofago's sound.
December 2000 saw the release of their next opus, Genesis, a conceptual album about the creation of delimited objects from a single point.
