Yeah its definitely not a sound that tons of people are probably gonna like to listen to. I doubt Caamp will be for you either. By and By is my favorite of theirs.
Id say most i listed may not be for you, but gotta try them at least. I used to never listen to any of this type of music until maybe 5 years ago or so.
i liked caamp a lot more. maybe not enough to add him to my library but much more my speed.now this i'm really into. already added this album to my library and will likely listen though a few albums before moving on.
skipped over a few recommendations that were described as folk. now i'm on Oliver Tree's "Cowboy Tears Drown the World in a Swimming Pool of Sorrow (Deluxe)"
i wouldn't say it's the same but for me this scratches the same itch as built to spill for me. if you decided to look them up start with "keep it like a secret" or "there's nothing wrong with love". there sound evolved after that and not necessarily for the better.
