Has anyone thought about these in any more depth than just taking them at face value with the record? There are obvious noises such as that of the film reel at the beginning of I Want To Kill You Like They Do In The Movies, but there are other more subtle parts, like the spoken word sample (nearly indecipherable) behind Four Rusted Horses, or the "submarine" radar (or perhaps medical equipment) at the close of Pretty As A Swastika.
Also, the buzz that features both at the beginning of We're From America, and recurring on the official website, it sounds interesting. If you listen to a song called A Stranger from A Perfect Circle's Thirteenth Step, at 2:03 in there is a noise that sounds very similar. I'd be interested to know if that has anything to do with Twiggy's involvement on that record as Jeordie White... If you'd like to listen to the song:-
