Mutilator was formed in 1985 in Belo Horizonte by vocalist/guitarist Kleber, guitarist/lyricist Alexander "Magoo", bassist Ricardo Neves and his brother Rodrigo on drums,[1] originally under the name of Desaster.
The album was recorded on a tiny budget but has proved to have some long-lasting appeal; Eduardo Rivadavia of Allmusic describes it as "an excellent case study in DIY ethics and the desire to succeed against all odds" and comments, "when held up against its improbable origins, many of its deficiencies can't help but be ignored, and may well explain the album's enduring appeal in the eyes of serious metal collectors".
Magoo however had faith in Mutilator's future potential and turned down an offer to replace Jairo T. in Sepultura (a position eventually taken by Andreas Kisser).
Magoo took over on vocals, also penning all of the lyrics and much of the music; the record also saw the arrival of new members CM (on guitars) and drummer Armando Sampaio (ex-Holocausto).
Recorded and mixed in 16 tracks at Belo Horizonte's JG Studios, the album "held the distinction of being Brazilian heavy metal's most professional domestic production yet".
