[1] Arkley first gained attention as a member (and leader) of Christian thrash metal band Seventh Angel.

After Seventh Angel split, Arkley formed Ashen Mortality, adopting a doomier style mixed with mediaeval influences and some death vocals.

[3] Arkley was briefly a member of the Australian doom band Paramaecium and recorded the album A Time to Mourn with them.

[4] Drawing on similar influences to Ashen Mortality, My Silent Wake is a more experimental progression for Arkley, with more open soundscape arrangements, but also a heavier aspect to the sound.

Arkley is also involved in a collaboration with the Visionaire frontman in a band called Century Sleeper who released Awaken in 2006.
