OZ, pioneers of European heavy metal from Nakilla (Finland, 1977), return with the reissue of Decibel Storm (1985), their fourth studio album. After notable beginnings with OZ (1982), Fire In The Brain (1983) and III Warning (1984), this record confirms their influence on the Scandinavian metal scene. The reissue benefits from a transfer, restoration and mastering carried out by Patrick W. Engel at the Temple of Disharmony in April 2025, offering optimal sound to rediscover this classic of European heavy metal.
