What is the name of the track that plays before the Geth Armature fight on Therum?

Question

The other night my friend was having me listen to samples from the Mass Effect soundtrack(s) (she said there was more then 1 for the first game) that she was going to get me, making sure that I actually did want them.

While the samples had music I've wanted to listen to for a while, one track seemed to be elusive and that was the background music that plays on Therum between when you have to get out of the Mako and proceed on foot (where you have that small gap in the rock) and the Geth Armature.

She had me listen to 2 soundtracks and given the soundtrack grouping she's said it's odd it's not in there. One soundtrack listed the following:

Track No	Title
10	Spectre Induction
11	Liara's World
12	A Very Dangerous Place
13	Feros

While another listed them as:

Track No	Title
20	Speech Hardass
21	Liara's World
22	A Very Dangerous Place
23	Feros

In both Liara's World, sounded like the music that plays when you're in the Mako heading to the ruins where Liara should be, while A Very Dangerous Place sound like the battle with the Geth Armature. It could be in another track, but I haven't recognized it from the samples

So what is the name of the track that plays before the Geth Armature fight on Therum?

Answer 1

It doesn't have a useful name

As you note, this track has not been released to the public. The first track listing you provide is from the retail OST:

But this is far from a complete soundtrack, and omits many tracks from many locations (the Flux nightclub music springs to mind most immediately).

The second track listing, I believe, comes from the so-called "Mass Effect Expanded Soundtrack", from khinsider.com. This listing includes many tracks not on the official release¹ and, while it doesn't actually include this exact track, it has something similar in track 29, "Knossos"; that one appears to be a medley of four very similar tracks from the game files. The bit most similar to what you're looking for comes at the end of that track, but isn't quite the same.

The closest thing to an official name is the track's filename, mus_area_knossos_v2_1_jack (Knossos being the name of the star system containing Therum; I believe "jack" is a reference to Jack Wall, the game's composer); not exactly a catchy title.

Several people have taken the audio files directly from the game and uploaded them to YouTube (and other places, I'm sure); they typically call it some variation of "Therum Battle" or "Therum Theme". For example:

I'm not exactly willing to re-play the game myself to verify that this is the correct track, but YouTube Let's Play videos can do it for me; consider this one, for example, where you can hear the track start to come in at about 30:13:

So that's as close as you're going to get to anything useful.

¹ Since this is a fansite (actually a Kingdom Hearts fansite, albeit one with an extensive video game music library attached), it's likely that these are ripped from the game files. I can't begin to speculate on why only these tracks were ripped, or where the names came from
