Interestingly, listening to the Pyre soundtrack outside of the context of the game and its worldbuilding, my sensation of what the instrumentation is doing is totally different. For example, I didn't notice the bass guitar as a /thing/ while playing, but listening now it's actually super prominent.
"Dread Design" (music for the Pit of Milithe) is pretty atypical of the soundtrack generally, but gosh, those spooky synth hits give me feelings

This also has a lot more in common with the Transistor soundtrack than I realized while playing.
