The album was released on Earache Records: Mosh 13 in 1989. In 2005 a re-issue was released by Earache, featuring new artwork. The band advises not to buy the re-issue, as they have not been involved and will not get royalties.
Realm of Chaos displays a progression from its previous output in speed and riffage. There is a strong focus on blast beats in many of the songs, with chaotic guitar soloing, common in grindcore. Nevertheless the signature heavy riffing is also apparent. Thus, this is usually considered a death metal album, or a deathgrind album (a fusion of death metal and grindcore).
