MATHYR was founded in 2000 by Sagrim and Phlegiaz who had already played together in various bands before. Short time later Chris (b, voc) joined the band and contributed his share to form the music and appearance of MATHYR decisively. This was core-ensemble plus another guitarist who had to leave the band because of personal reasons. Later on he was replaced by Thorson in 2003. MATHYR performed numerous gigs for example with Dew-Scented, Disillusion, Heaven Shall Burn, Hypnos and many more.
