In 1999 Mika Lammassaari, his cousin Aki Lammassaari, Juha Haapala and some of their friends started to play covers from Pantera, White Zombie, Metallica, Sentenced, etc...
During -99/2000 Mika, Aki and Haapala made some songs of their own under the name of Zilstrone. These songs were put together and a demo CD was recorded with help of Kari Räty who did the recording, mixing and mastering. He also played the bass lines for the demo.
Jarno "Jarski" Rankinen joined the band in summer 2000. Jarski, Mika, Haapala and Jukka-Pekka Ellilä (guitarist) started a project with a goal to play more agressive metal in the form of covers first. At this time Aki decided to leave the band 'cause his goals were in different kind of music.
This project band made four songs of their own and in the summer 2002 Antti "Hape" Haapsamo joined them. Soon after that Ellilä didn't have enough time for the band, so Jarkko Kaleva replaced him. Mors Subita was chosen to be the name of this group. New songs were made in pretty fast phase and during spring 2003 Mors Subita recorded their first demo which was called Synopsis.
During the year 2004 Mors Subita made few gigs and at 2005 Mika, Jarski and Kaleva started their militaryservice. At the end of the 2005 Jarski decided to leave the band. Rather soon after that Mika "June" Junttila did step in the line as a new bass player.
2006 military service of the guys was done and Mors Subita made their 2nd demo-MCD “Epoch†after which the band has done great gigs and new material.
