Influenced by Dissection, Marduk, Dark Funeral, In Battle, Dismember, and the like, in 1997 their Where Only the Seasons Mark the Paths of Time would showcase the band's belligerent old-school black metal. The album was not just a landmark for Thy Primordial but the industry as well for it would become the first non-major release to benefit from the 20 bit recording technology that was now available.
Their third effort's release was delayed due to the aforementioned arrival of the debut recorded two years previous, but At the World of Untrodden Wonder would eventually emerge in 1998 with an 18-page booklet, clearer vocals and their debut T-Shirt. The follow-up album, The Heresy of An Age of Reason (1999) took only five weeks to complete the eight tracks but within a year rumors were abound that 'Pulverised's' three album contract with the band was now fulfilled and Thy Primordial, clad in spikes, paint and leather, and featuring the membership of Jonas Albrektsson (bass), Mikael Andersson (guitar), Isidor (Real Name: Andreas Karlsson; vocals), Nisse Nilsson (guitar) and Morth (Real Name: Jocke Pattersson; drums), were seeking a new home, even asking Canada's 'Emperor Multimedia' for interest. 'Emperor' took them seriously but not signed as 'Emperor' was, back then, a struggling start-up itself. Thy Primordial was also facing their first membership change with N. Nilsson choosing to leave.
After signing to 'Blackend/PHD' (UK) their new album, The Crowning Carnage was released in March of 2002.
Isidor would be the next member to leave. Nicke Holstenson (ex-Nominon) was selected to take his place for 2003's Pestilence Upon Mankind. Morth, for his part, had drummed for Unmoored on the side during the sessions for their Kingdoms Of Greed album, and added production credits with their previous Cimmerian opus. Two years later, Thy Primordial called it quits. Two compilations were released posthumously in the form of The Blackend Years (2018) and ...to Ruin and Decay the Final Harvest (2022).
Footnote: during the life of Thy Primordial several members engaged in a side project with members of Mithotyn called Indungeon.
