There are several bands called Mythos. 1) New-Age from Canada.
2) Death Metal from Finland.
3) Krautrock/Progressive Rock from Germany. 1) Mythos is a new-age band that plays semi-acoustic instrumental music that combines various Western styles; female vocals are used as just another instrument. Most of their tracks are contemplative, often slightly sad, with finely detailed sound. The band was founded by two Canadians, Bob D'Eith (keyboards) and Paul Schmidt (guitar); both received classical training on their respective instruments.
