Ultramayhem Org. was baptised in summer 2004 but the seed of UltraMayhem was implanted way before. First signs of an organised UltraMayhem were seen back in 1998 when a bunch of Metalheads joined forces to 'mayhemize' the Metal scene. The result was UltraMayhem Organisation, a Metal band which desired to refine the core of Metal and build a new standard for modern Metal by doing things the way others dare not to.
UltraMayhem Org. released their first Promo EP, Excuses to Start a War, autumn 2004 and it recieved exciting reviews in Finnish Metal media. After that, there was some changes in the organisational structure, but it only made the ba nd stronger and more talented. UltraMayhem Organisation would release a single in 2006 titled UltraMayhem - Symposium on March 31st of that year, and it's sequel UltraMayhem - Symposium II on May 31st that same year under the membership of Kill Hill, Vlad Tepez, Johnny Stoner, Ron Autero, and Miquel De La Muerte and influences of Faith No More, System of a Down, Pantera, Dimmu Borgir, Slayer.
