This was supposed to be a hidden album which is linked to from various songs in Quarantine. If somebody clicked on the link, they will be presented with these 4 sound files which are less music and more an experiments in atmosphere.
The FM audio includes a sample from 96.7 FM mystery in Portland Oregon. Where people reported strange sounds happening sometimes on the radio station. Here is an LBRY link to a video about this mystery by Nexpo.
1941 ( a 1979 Steven Spielberg action comedy film ) seems like a parody of Michael Bay. The film's credits literally have explosions happen all throughout, under the scrolling text. There is so much colorful destruction, so much over the top action scenes, so much loud over-bombardment, that I believe this is the Ultimate Steven Spielberg film.
