A dramatic project band including some true heavyweights of the Metal scene. EIBON include in its ranks PANTERA frontman Phil Anselmo, Fenriz of DARKTHRONE, Killjoy of NECROPHAGIA, Satyr Wongraven of SATYRICON and MAYHEM's Maniac. EIBON debuted deliberately low key with a solitary track on the 'Moonfog 2000' compilation album.

Killjoy, retaining his union with Maniac, would put an end to EIBON forging a fresh old school Black Metal endeavour WURDULAK for the November 2001 debut 'Ceremony' In Flames'. WURDULAK would include BLOODTHORN drummer Jehmod, SOUL FORSAKEN guitarist Fug, GORELORD / DERIDE and NECROPHAGIA guitarist Frediablo, PERISHED guitarist Ihzahg and IMMORTAL bassist Iscariah.

Killjoy's stamina for band projects was further tested with the introduction in the summer of 2002 of Black Metal band HELL PIG, a collaboration with SLIPKNOT drummer and MURDERDOLLS guitarist Joey Jordison.

In August 2009 it was learned that Maniac had united with Andrew Liles (a.k.a. "Ripping Penis" / "Pig Slaughter"), of CURRENT 93, NURSE WITH WOUND and SEHNSUCHT, plus Czral (Carl-Michael Eide), of VIRUS, DIMMU BORGIR, SATYRICON, VED BUENS ENDE, AURA NOIR and DØDHEIMSGARD repute, to release an album that he and Czral had begun working on in 1996. The resulting album, 'Det Skjedde Noe Når Du Var I Belgia' (English translation: "Something Happened While You Were In Belgium"), credited simply to MANIAC/LILES/CZRAL, was made available on the U.K.'s Dirter label.
