[edit] Lyrics

Brus-kuluz taurzur bûrzu tiil-ob
Hush-ob dhurum agh ufum dhurum
Tor Vautu brus-troguz
Urgai-u gukh dûmp agh tiimor

Talaan-u rûk-ir tor urûk
Nauru-ir agh kragoru nûrsu grishûrz
Nork-ulu furtun agh goth
Mordor-ob bot-tuk

Ghaash agh akûl û Nazgûl skoiz
Mirdautas vras!
Karn ghaamp agh nût
Shaut Manwû quiinubat gukh

English translation:

Dark have been my dreams of late
Of secret doubt and secret fear
A thousand years have passed away
To lay down doom and terror

To north ride on, a thousand orcs
On wolves with giant bloody fangs
They take the storm and power
Of Mordor through the world

Fire and Ice, the Nazgûl fly
It is a good day to kill!
(Painted) red is Earth and sky
Even Manwë will bow down
