Illuminaudio is the track that was released in the initial video, that got everyone stoked for the new tunes. Nice and slow, sets the stage for what's to come.
Caves starts out with heavy drums, so deep and full sounding. This is the first display of Brandon's range on the album, going from his impressive deep screams, falsetto, and harmonies. If anyone was to replace Craig they found the right guy, he can sing like a champ. I could see this being another single down the road.
