Im going to take the opportunity music is being mentioned here and gravedig/hijack this thread.
I just downloaded the FO2 Soundtrack, and wow, listening to this in Surround Sound quite loudly is amazing.
Who made the music for FO2? Its so creepy. It just gets the entire atmoshpere so well.
For example, when I first walked in to Gecko, and 'Industrial Junk' (Track 7) started playing. I mean, that is some creepy shit. That, the fact it was night time, that ghouls are ugly as fuck, and that I had been told the city was an undead nightmate which would welcome me with hostility. I find sounds scare me more than what I see, so this did it for me.
But my favourite one so far is 'Vats of Goo' (Track 5), which starts off incredibly grim and is generally found at pre-war military locations (such as SAD, EPA, Etc..) I love the grim militarism of it, with its air raid sirens and militaristic drums. It reminds me of the futility of war, especially when nukes are involved, and the fact its also the intro song of FO1 just makes me think of the 'futility' of the ancients who went to war over resources.
'All Clear Signal' (Track 16) is also pretty good. I like how most of the music is generally depressing and grim, sets the atmosphere of FO very well. There is also generally a distorted and deep voice recognisable in some seconds of these songs.
They sure don't make music like they used to.
