 The band currently consists of Richie Cavalera (vocals), Christopher EL (bass guitar) and Lennon Lopez (drums).
 Frontman Richie Cavalera is best known as the stepson of former Sepultura and Nailbomb, and current Soulfly and Cavalera Conspiracy frontman Max Cavalera.
Violent by Nature was the second and final album from Arizona thrash metal band, Atrophy.
 It was released on Roadrunner Records – like its predecessor, "Socialized Hate" – in 1990.
 Again, the album was co-produced by prolific producer/engineer, Bill Metoyer.
 The band made the journey from Arizona to California to record it.
 They followed up with tours of the USA and Europe with the likes of Sacred Reich and Coroner, but shortly after, Chris Lykins left the band to pursue a medical school course and the band split up after Roadrunner Records lost confidence in the band because of the departure of one of its leading songwriters.
  The model for the artwork is Richie Bujinowski (now Cavalera), who would later become Max Cavalera's adopted stepson and frontman of Incite.

Roots is the sixth studio album by Brazilian heavy metal band Sepultura.
 It was released in Europe on  20, 1996 (1996--) and in the U.S. three weeks later on March 12 by Roadrunner Records.
 It is the band's last studio album to feature founding member and vocalist/rhythm guitarist Max Cavalera.
 Following the shift to slower tempos and Latin-tinged rhythms on the album "Chaos A.D.", "Roots" delves even further into Brazilian musical textures and features significant contributions from Brazilian musician Carlinhos Brown, who guided and arranged the sections throughout the album that feature ensemble percussion playing.
 The song "Lookaway" also features guest appearances by Korn vocalist Jonathan Davis, former Korn drummer David Silveria, former Limp Bizkit turntablist DJ Lethal, and Faith No More/Mr. Bungle/Tomahawk/Fantômas vocalist Mike Patton.
 The album draws influence from the then-surging nu metal movement, specifically Korn (whose first two albums were also produced by Ross Robinson) and Deftones.
 (After leaving the band, Max Cavalera would continue to pursue the nu metal and "world" stylings of "Roots" with his solo project Soulfly.)
 Since its release, "Roots" has sold over 2 million copies worldwide.
