Re: Scary music!
"Still"-Esbjorn Svennson Trio
"Climbing up the Walls"-Radiohead
"Adagio Ma Non Troppo"-Charles Mingus
Also, one time I took a nap and woke up with Penderecki playing really loud. That was moderately terrifying. Grogginess just sort of amplifies everything. I was really confused.
I do like the idea of scary music though. I think it's really difficult to make music that's truly scary on its own, so when it happens it's quite an accomplishment.
