[5] After their first demo, entitled Black Seared Heart, Sir Vereda left the band[5] due to legal problems,[citation needed] and was replaced by Dirge Rep.

[5] In 1994, Necromantic Gallery Productions released Gehenna's first 7-inch EP Ancestor of the Darkly Sky, and the band signed and cancelled a deal with No Fashion Records; they entered a studio to record a full-length album in January 1994, but it was "cancelled due to NFR's lack of money".

Three uncompleted songs from this studio session appear on the re-release of the Black Seared Heart demo via Holycaust Records.

They played at "the legendary Zonen concert, which led to the appearance on the now 'cult' norwegian Black Metal documentary 'Det Svarte Alvor'".

Gehenna were joined by Sarcana in 1994 and played at a festival held at Lusa Lottes Metal Pub, Oslo, with Dark Funeral, Gorgoroth, Dissection and Enslaved.

Gehenna signed with Moonfog Productions, who released the EP Deadlights and the album Adimiron Black (featuring Sarcana on the title track and "Eater of the Dead") in 1998.

Gehenna performed at By:larm Stavanger, Zone Trondheim, Inferno Metal Festival and Codevilla, Thunder Road (Milano).

In 2012, Dirge Rep left the band again after their show at the Wacken Open Air festival in Germany and was immediately replaced by Slaktaren.

This was Skinndød and Slaktaren's first recordings for Gehenna and the band's first album to feature Sanrabb as the only lead vocalist.

Jackie Smit of Chronicles of Chaos called Gehenna's second album, Malice, "a sterling example of symphonic black metal".

[4] According to Smit, Murder was "a misguided attempt at a death metal record", which disappointed many fans of the band's earlier style.

[6] Yet WW was "not so much a black metal phoenix rising from the ashes, but a band completely redefining their philosophy toward songwriting […], choosing […] to throw its lot in with the grim sounds of Darkthrone and Burzum.

Indeed the record's harsh, raw guitar tone is very similar to the one that gave Hvis Lyset Tar Oss such a maleficent feel, while Dolgar's vocals drip with an unnerving and coarse hatred as the band hammer out their themes of war and destruction at a frenetic pace.
