There is no telling exactly what you will hear on this station. Maybe an obscure track from an old horror movie soundtrack. Maybe a Dr. Demento song parody. You will certainly run into vintage movie trailers and odd retro commercials. Perhaps you will tune in, as I am right now, and find something in the style of an old timey radio show which is either an adaptation of an H.P. Lovecraft story or an original production based on the Cthulhu mythos.*
They have live shows on Saturdays. I cannot vouch for those. But their regular programming is amazing. Very well curated with some extremely offbeat stuff which makes a wonderful backdrop for these dark eldritch evenings leading up to All Hallows' Eve. I love it because it has completely random transitions. Everything feels like late night, bleary headed discovery.
*Turns out the program in question was an adaptation of The Return of the Sorcerer by Clark Ashton Smith which originally appeared as part of the Suspense revival on Sirius XM.
Like I said these fuckers dig deep.
