The story of Kalmah begun in 1991 when Pekka Kokko and Petri Sankala founded Ancestor. After 2 demos Antti Kokko joined the band to handle the position of lead guitarist. In 1998 after all in all 5 melodic trash/speed/death metal demos and 5 different bass players it was time to clear the table. Acenstor was buried and refounded as Kalmah. The Line-up was completed by keyboard player Pasi Hiltula.
