Thank you so much for writing about this - and so brilliantly. I've wondered for a long time what you'd make of the play. Between the toxic mansoup (I like Collinson alone out of them, but he's no use to Jill in the end) and the ragstone record, it still disturbs me, and the question perhaps that unsettles me the most; is the "willemite-green" ghost only a recording, or somehow conscious? I hope you're right, and it's the former.

One of the books I bought at the weekend chimes in with this post; David Toop's Sinister Resonance. It's a history of listening that treats sound as ghost, listener as medium. I've not read it yet, but looked in the index: no mention of The Stone Tape.
