Ceremonial Oath is a Swedishextreme metal band who formed in 1989 under the name "Desecrator", changed their name to Ceremonial Oath in 1991 and disbanded in 1995. During their short career they released three demos, one EP and two full-length albums. Their influence is greater than their short lifespan suggests: several of the band members would later create or join metal bands that would gain fame and fortune on the future metal scene, such as In Flames, an influential band to the melodic death metal genre; and Hammerfall, a band who would greatly influence the awakened interest in power metal and traditional heavy metal.
Ceremonial Oath will reunite for an appearance at the inaugural edition of The Gothenburg Sound festival, set to take place January 5-6, 2013 at Trädgår’n in Gothenburg, Sweden. In addition to that, a remixed and remastered version of the 1993 album The Book of Truth will be re-released at the end of 2012.
