The songs "Against", "Choke" and "Tribus" were released as singles, with a music video accompanying "Choke". The video featured footage from the "Barulho Contra Fome" ("Noise Against Hunger") concert that was the first gig of the "Against" tour. This performance included guest appearances from the Xavantes tribe, who had featured on "Roots" (as documented in the "Choke" video) as well as Mike Patton, Jason Newsted, Carlinhos Brown, original Sepultura guitarist Jairo Guedz and Coffin Joe (whose "blessing" of the band performed during this concert turned up as a B-side entitled "Prenúncio" on the "Tribus" EP).
