After a debut mcd, SETH’s first album "Les Blessures de l'Ame" (released in 1998 on Season of Mist) quickly appeared as a leading act in the extreme French metal scene harvesting very promising reviews from the press and being the starting point of a solid fanbase worldwide that has been expanding since then.
Adopting a much more professional attitude than many of its BM counterparts at the time, the band signed a two-album deal with Osmose Productions and recorded a second album "The Excellence"(2000). Fortified by prestigious collaborations such as Fenriz (Dark Throne) and the famous electronic band Total Eclipse, SETH combined different influences with no real boundaries. Shortly after that, the band got offers to appear on French TV music shows and shot a video clip for the French MTV channel "MCM".
SETH was then invited to take part of the legendary "Tribute to Mayhem" compilation on Avantgarde Music along with bands such as Immortal, Behemoth, or Dark Funeral. In 2002, the band recorded its 3rd album "Divine X" at Excess Studio in Rotterdam (Sinister, Elegy, After Forever, Epica) again on Osmose Productions.
This release showed the band’s undisputed ability to mix both dark atmospheres and brutality. The album was critically acclaimed, receiving top-rank reviews in many magazines like Mindview and Grindzone.
In December 2003 the band entered again Excess Studio in NL with a revised line up, featuring new members Cyriex and Black Messiah, to record its most mature, personal and mesmerizing album ever: "Era Decay".
After the 4th full-length album, the band entered a significant break in 2005. Nevertheless they created a surprise by playing an exclusive show in Germany in September 2011 headlining together with the legendary Bethlehem. Shortly, the band resigned on its original label Season of Mist to reissue its first album "Les Blessures de L'Âme" and released one year later in June 2013 its new critically acclaimed album entitled "The Howling Spirit" on the same label, which marked the return of the band after a seven-year break. Seth recently embarked a three-week European tour together with death metal gods Pestilence and registered its first live album at Les Feux de Beltane (Brittany) in May 2019.
