At the beginning of the year 2002, in a small and damp rehearsal room in the town of Falun, Sweden, three musicians decided to kill some time with a rehearsal session. Erik Skoglund (ex-Five More Victims; vocals), Björn Åströ+m (ex-Bludge; drums) and Ola Berg (ex-Without Grief; bass) felt after playing a couple of hours that a band should be formed. After completing two songs the band and the style of music was a fact. Naming the band after the first song they had written, the Grindcore styled ensemble Gridlock saw the light of day.
After another session they felt that the sound was lacking a pair of strings so, guitarist and vocalist Nicklas Lindh (who had played with Ola in Without Grief) joined. Shortly after that a two-song demo was recorded. It was never intended to be sent to any labels or magazines, instead the band concentrated on writing more material. They included influences from genres such as Death and Thrash, and in addition to the creation of new material the band also started the search for a new name since their original was already well represented by others. After stumbling on a newspaper article about a group of kids in Australia who, in pure boredom, had started to amuse themselves with arson, the hunt for a name was over; the headline of the article read 21 Lucifers.
After concluding one gig and another demo recording Erik felt that he would rather concentrate solely on the vocals instead of both vocals and guitar. So another old Without Grief member, Tobias Ols joined. Now five-man ensemble book two days worth of recording time at Jonas Kjellgrens' Black Lounge studio . The result: a five-track demo entitled Retaliation (2002).
