little less thrash oriented and fully embracing their groove metal influences with the incorporation of drop C tuning, a five string bass, clean vocal choruses and even a rap metal track called "Chalito", serving also as a bridge between their previous more generation X oriented sound and the more millennial oriented sound they would embrace in later releases. With this album, the band headlined a show in Obras Sanitarias for the first and only time, and they also opened for Sepultura in the middle of their Roots tour at the same venue. By 1997, Martín Carrizo left the band while he was under contract for their new album recordings, so while they recruited Andrés "El Niño" Vilanova as their new drummer and went on to the Indigo Ranch andy hired Jimmy DeGrasso as a guest drummer to record Poder Latino which was produced by Max Cavalera and is considered by a lot of fans to be their best release and the band's big break. 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. The album included lot of guest musicians such as Metallica's Robert Trujillo, Fear Factory's Christian Olde Wolbers and Argentinian folk musicians Leon Gieco and Chango Farias Gomez. 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). During that period of time, the band toured all over Latin America and made their two biggest shows to date as headliners at Buenos Aires Vivo in front of 35,000 people, at the Velodromo of Buenos Aires in front of 15,000 people and then closed that year at Parque Sarmiento in front of 7,000 people. In 1999 the band returned to Indigo Ranch in Los Angeles to record Usa Toda Tu Fuerza, which was produced by Richard Kaplan and Chuck Johnson, and dug deeper into the band's newfound nu metal influences. The album included a Spanglish version of AC/DC's Highway to Hell featuring Lemmy Kilmister from Motörhead. In 2000 the band toured in the United States as a part of the Warped Tour festival, alongside the likes of Green Day, No Doubt, NOFX, Papa Roach, Millencolin and many
