A.N.I.M.A.L.

[2] The band experienced commercial success in the mid-to-late 1990s and toured throughout a number of Latin American countries, the United States and Europe, and also opened for numerous big names from the worldwide rock and metal scene such as Pantera, Biohazard, Bad Religion, Ratos de Porão, Suicidal Tendencies, Sepultura, Soulfly, Megadeth and Slipknot.

[2] In 1991 Gimenez recruited Marcelo "Corvata" Corvalán as their new bassist and then recorded their self-titled debut album, which (unlike later releases) had a more classic heavy metal oriented sound with some mild grunge influences.

[2] That album was the beginning of their rise to fame, as they sold out Cemento, (a defunct rock concert hall in Buenos Aires, Argentina), numerous times and opened for Suicidal Tendencies and, once again, Pantera.

Once again their sound changed, this time their influences were much closer to the likes of Korn, Coal Chamber, Soulfly and the rising nu metal scene, with bouncing riffs, rap verses, melodic choruses and the drop A tuning.

It also includes 3 covers at the later part of the album: "Cop Killer" (originally by Body Count), "Fuerza Para Aguantar" ("Strength To Endure" by The Ramones) and "Cinco Siglos Igual" (Leon Gieco).
