Anthology

I disagree about the band ending their run, or that this song indicates that. Thrice has long shewn a tendency to "start from scratch," by putting their old stuff to bed and revisiting themes and their personal meanings. Melting Point of Wax got revisited with Daedalus, for example. Their sound has repeatedly been given a clean slate through a rather unorthodox cleansing, most notably the Alchemy Index setting the stage for their most recent sound.

The theme of Anthology is to use something old, or several old things, and make them into something new. It's not an uncommon writing exercise to review how a character or a line strikes the writer just as much as the reader. Surely the understanding that a book or song or poem might mean something different to you as an adult as when you were a child can apply to the person who wrote it.

In the case of this song, those lines that might have applied to something abstract or ephemeral when Dustin was younger now have a much more concrete meaning. So the lines such as "I'm sure you could snap my neck, but I trust you'll save my life instead" applied to God or something else when he wrote Trust, but now apply to his wife or his children. But putting those songs to bed by revisiting their relevance to him doesn't indicate to me that the band is ending.
