After releasing four demos and an EP and signing with Rage of Achilles, Omnium Gatherum released their debut full-length album
Spirits and August Light in April 2003, which gave the band some attention within the underground metal community and the press. Next, the band signed to the major metal label
Nuclear Blast in the autumn of 2004 to release their second album
Years in Waste. This album was more technical and
progressive than their earlier releases. In the summer of 2008, bassist Eerik Purdon announced that he was leaving Omnium Gatherum, and in 2009 Toni Mäki officially joined the band as their new bassist. In August 2010, Omnium Gatherum announced that they had signed a deal with
Lifeforce Records for their next release, and that their longtime rhythm guitarist Harri Pikka had left the band. Their official statement read "We're really sorry to announce also that Harri Pikka has silently decided to flee the OG crew after 13 years of solid service. We don't know his exact reasons for this but maybe someday mr. Mystery Man tells us… :) At the moment we've decided to finish the new album as a 5-piece unit, but we have the best possible live guitar unit called Joonas Koto (Malpractice / Ex-To/Die/For / Ex-Hateframe) filling the second guitar live duties at the moment and it rocks!" Omnium Gatherum entered the studio to record their fifth studio album for an early 2011 release. Lead guitarist Markus Vanhala handled all guitar parts for the recording. Mixing and mastering were handled by Dan Swanö. Their fifth album,
New World Shadows, was released in Germany, Austria and Switzerland on 4 February 2011, in Finland, Sweden and Hungary on 9 February, the rest of Europe on 7 February, and North America on 1 March. It topped the Finnish album charts and was on the fifth position on the official national album chart, as well as placing first on the Finnish Rumba indie chart. On 10 July 2015, the band announced that they had almost finished the recordings for a new album. The album,
Grey Heavens, was released in 2016. In 2021, Omnium Gatherum released their ninth studio album,
Origin, and announced a North American tour supported by
Allegaeon and
Black Crown Initiate. == Band members ==
