What Music style, Bands or songs do you think of when meeting with a Falout Universe specific faction?

One example for me is the Followers of the Apocalypse and hippie flower power music like Fleetwood Mac. I could totally see Stevie Nicks acting like Julie Farkas.

I think the guys at Bethesda hit the nail on the head with the Legions theme. It's like a depressing violin mixed with a stern undertone, which describes the Legion perfectly. As far as songs from real life goes, I can't really think of anything for the Legion. I know most people with go with metal or something equally brutal because the Legion is brutal, but I think subtly is more chilling to me.

I dunno but I listened to Beatles - Roll Over Beethoven while playing Dead Island and whenever I play Dead Island I think of Beatles and whenever I listen to Beatles I think of Dead Island.

So uh... Legion... Madonna.

Ha!
