Track composed by Alexander Brandon
This music plays when you infiltrate an MJ12 stronghold situated in a cathedral called Cathedrale de Payens. "Payens" is a reference to Hugues de Payens, the first Grandmaster of the Knights Templar. The cathedral is also the place where everybody's orange soda-loving agent, Gunther Hermann dies. If JC Denton gets knowledge of Gunther's killphrase, "Laputan Machine", JC can quickly end Gunther's life. This is how the dialogue plays out:
I know your UNATCO killphrase: Laputan machine.
I am not a mach -
Sticks and stones.
The Paris Cathedral UMX is split into six parts. I've taken the first part since you get to hear a pretty cool, minimalist organ version of the Deus Ex theme (man, it shouldn't be Guile's Theme Goes With Everything, it should be Deus Ex!). I've also taken the fifth part (1:59) which I believe is the heroic and cool conversation music and the sixth part (2:53) which I believe plays when you leave the scene.
