I’m currently working my way through the first five Lovecraftian Obsession podcasts, the fifth of which has just been released. These are long and intelligent in-depth interviews, by author Rick Dakan, with people who really know their Lovecraft. Very enjoyable.
For other free audio, I also recently found the BBC Radio 3 “Weird Tales” documentary has been nicely fan-illustrated on YouTube.
And if you’re in the UK (and only in the UK, as the BBC website gets all huffy and fascistic if it detects you’re outside the UK) there’s a new 45 minute “In Our Time” round-table on the science and history of the exploration of Antarctica. Much more on the discovery of the science and geology than the human and technological story of the early expeditions, sadly.
