With 10,000 Days, I don't consider Lipan Conjuring filler at all. To me, it serves a purpose. It's the backstory to why the guy in Lost Keys is in the hospital tripping balls and could be why it's subtitled "Blame Hoffman". The person took LSD and it led them to a journey to find spiritual enlightenment, just taking LSD wasn't enough. They then discovered a way to "achieve" it by visiting a native American shaman from the Lipan tribe. Whatever happened was too much for them, hence the loud scream at the end of Lipan Conjuring, and it caused them to get taken to a hospital. As he lays there, he relays to the doctor everything he experienced while being under and it's coming across as 3 different languages (the many different vocal effects in Maynard's vocals), like how the Rosetta Stone is, Rosetta Stoned is trying to decipher your experience while under the effect of psychedelics, it comes out as something a person needs to decipher to understand what the hell your trying to talk about.
