the band's first record "om pushne namah", was released in 1983, and is different from most early extreme metal in that the lyrics were sung in portuguese, not english. the release of this album also marks the departure of jose piloni (drums) from the band. in this early period, it was very difficult to secure live performances, and the band had to produce their own shows, and promotion was limited to pasting up posters, but vulcano persevered, and moved forward in 1984 to release the demo "devil on my roof".
