Yeah, this isn't my upload, but here is a bootleg of the 21st Century songs played during the California club gig.
Be warned though, the quality is really shitty, i mean, much worse then the videos that Camila posted, so keep an open mind until you hear the actual album version of the tracks. You'll be able to get a feel of the songs, but probably won't be able to make out a lot of the lyrics (kind of like the first bootleg of Hammerhead during Summersonic).
So far, based off the videos and this bootleg, Last Night On Earth, Peacemaker and Christian Inferno are my favorite so far.
Edit: Some songs from this album seem to have this really cool Warning vibe about them.
Edit II: Drama Queen is also a pretty catchy song: in the bootleg, it kind of sounds like security was taking the camera of the people beside the recorder.
