Ooooooh man now this is a good question. Fish is definitely your best place to start, since she’s the only one I can think of who did a full ALBUM of post-apocalyptic (and pre-apocalyptic) filk, AND THEN SOME.
Me and the brain mod went through and came up with as many as we could think of, besides everything on that album:
- “No Hurry,” by Vixy & Tony
- “Apocalypse Ballade,” by Araxie Haldane
- “All the Birds Are Gone,” by Talis Kimberley
- “Post-Apocalyptic Blues,” by Dr. Mary Crowell
- “We Protest the Robot Occupation,” Kari Maaren
- “A Lonely Christmas Out Here,” Kari Maaren
- Two (x, x) Seanan McGuire songs, though one’s unfortunately unrecorded and the other is on an album that’s out of print
- “What are We Doing,” by Alexander James Adams
- “Freedom of the Snow,” by Leslie Fish
- “Mount Tam,” by Leslie Fish (about trading one disaster for another)
- “Survivor’s Song,” by Julia Ecklar
- “Tribbles,” by Julia Ecklar LOOK THIS IS DEFINITELY AN APOCALYPSE
As always, everyone can feel free to add! I’m sure there are dozens more, at least.
