Oz is a pioneering Finnish Heavy Metal band that formed in the late 1970s and became one of the first Finnish metal acts to sign an international record deal, establishing themselves as key players in the early European metal movement.
The album The Oz, released in 1982 on the Tyfon Grammofon label, is the band's highly collectible debut full-length record.
Following their raw debut, Oz would gain greater prominence with subsequent albums, particularly the classic Fire in the Brain (1983), which offered a more refined sound while retaining the core aggression of their debut.
The album's enduring value lies in its authenticity as a foundational artifact of the genre. It captures a moment when heavy metal was still finding its form, existing somewhere between the hard rock of the 70s and the speed metal of the mid-80s. Collectors often seek out the original 1982 vinyl pressing due to its historical significance and the distinct sound of its original mix. The material on The Oz is a testament to the early global reach of heavy metal, proving that the energy and aggression of the New Wave of Heavy Metal was not confined to the UK, but was erupting in underground scenes across Europe, particularly in the Nordic countries.
Oz's music is a prime example of Early European Heavy Metal, Speed Metal, and NWOBHM-influenced Power Metal. This list features key contemporaries, regional pioneers, and bands that share their raw, early 80s metal sound and high collector appeal.
