The band was formed in the year 2000 in Sofia, Bulgaria by Bebo ( Nikolai Berberov ) and Chavo ( Chavdar Valchev ) . In the beginning they were using drum machines and samples and the songs were more industrial orientated.
One year later Roman joined the band as a live bass player with Kiril (drums) and Alexander (vocals). The band started playing more metal stuff without any programming whatsoever. In the year of 2003 they recorded their first 10 song demo at ''Graffiti'' studio in Bulgaria.
In 2004 the line up changed, Roman was replaced by Stan-G on the bass and Kiril was replaced by Koljo ( Nikola Nikolov ) on drums. Alexander quit and his place was taken by Dobata ( Dobromir Ganchev ) on vocals. At the time they were playing at local shows and venues in Bulgaria, also some shows in Romania, Turkey and Greece.
