Triptykon
Created in May 2008 to further develop the darkness invoked by its immediate precursors, seminal black/extreme metal pioneers Hellhammer and Celtic Frost, Triptykon evolved from a Celtic Frost side project initiated by Tom Gabriel Fischer (a.k.a. Tom Gabriel Warrior), the group's singer, guitarist, and main songwriter.

Following five years of songwriting and recording sessions, the subsequent release of their acclaimed Monotheist album, and a 125-date world tour, mounting tensions began to cripple the resplendently disinterred Celtic Frost by late 2007. The situation eventually rendered it virtually impossible for Warrior to succeed in convening Celtic Frost for songwriting and rehearsal sessions for the intended follow-up to Monotheist. Vastly disenchanted and loath to resign to inactivity, Warrior resolved to establish what was to be a temporary substitute project designed to develop, record, and perform the music and lyrics he envisioned for the projected album. The core of the initially unnamed group was completed by underground bassist Vanja Slajh (formerly of Swiss black metal project Freitod), a close friend from a past production project.

Very little of today's extreme metal scene would exist without the influence of Tom Gabriel Warrior. It's hard to imagine a heavier or more mesmerising band than Triptykon, and the marriage of Tom's charisma and some of the most pulverizing riffs ever written weaves sublime magic. A near-religious euphoria. - Metal Hammer UK
