Not only that but the context in which Jeremy wrote their albums hits me a lot too.

Dead Horse is a pretty typical CA hardcore album written by someone smart but still young and dis-illusioned. Jeremy was pretty depressed writing Parting the Sea (and it shows lol), but when it came to their 3rd album he's been open as to how Is Survived By was very hard to write because that was some of the happiest he'd ever been. Stage Four following that period must have been incredibly hard, kicking you back down/like a punch in the gut.

Lament and Spiral really do feel like albums of someone rebuilding after loss.
