band with Martex:
Enter Chaos (something between melodic swedish death and american death)
Immemorial (poor band, but with Martex on vocals. first album is symphonic black, second death. hint: Martex sang clean vocals too)
Luna Ad Noctum (fast lunar black. they have male vocalist, but Martex sang in 2 tracks with their vocalist. it's funny. he screaming, Martex growling )
other bands:
Sinister, Arch Enemy, Cadaveria, Opera IX, Symbolic Immortality (old polish death metal band. they recorded one album in '95 i guess), Occult (previous Rachel of Sinister band), Holy Moses
