Some things I've checked out recently:
NIGHTMARE magazine continues apace, strongly. They did a very nice reading of Ramsey Campbell's "The Companion" recently. Still trying to get Mr. Campbell or his people to respond to our emails:
http://nightmare-magazine.com/fiction/the-companion/DARK FICTION magazine just shifted editors:
http://www.darkfictionmagazine.co.uk/There is now the inevitable EDGAR ALLAN POECAST
http://poecast.co.uk/... as well as a podcast of readings of Ambrose Bierce (but no discussion) - THE PASSING SHOWMAN
http://www.thepassingshowman.com/home/Of these, I can recommend episode 2 "On A Mountain" and episode 6 "A Bottomless Grave" (the latter especially for those that enjoyed the black comedy approach of "Oil Of Dog" - the former is a nice bit of regional scene setting)
... as well as the inevitable Robert E. Howard podcast (with discussion), The Cromcast! I won't be following it myself, as I;m not a big Conan fan, but I'll probably check in when they get to Sailor Steve Costigan and Howard's horror fiction.
http://thecromcast.blogspot.com/Campfire Radio Theater, which is radio drama, has done a nice quality remake of 80's CBC classic horror radio drama's show NIGHTFALL's episode "The Dentist"
http://campfireradiotheater.podbean.com/For those who enjoyed episode 300 of PSEUDOPOD, there's a guy doing some very nice readings of E.F. Benson's ghost stories:
http://www.corvidae.co.uk/benson/index.htmlthe versions of "The Man Who Went Too Far" and "Negotium Perambulans" (either offered) are very nice.
Then there's Bedtime Tales: Stories for the Wayward and Churlish at:
http://podiobooks.com/title/bedtime-tales-stories-for-the-wayward-and-churlish/whiles the stories, in general, aren't what I'm looking for, I did enjoy the darkly comic two-parter "The Sitter" and, it must be said, the host has the most awesome voice ever!
And finally the oddly compelling Fiddleblack:
https://fiddleblack.org/podcastI like the dark ambient soundbed production on this and found one episode in particular, "Episode 3: The Bygone Campfire" to be a standout story!
