A really great old Radio-4 program here about "The Lincolnshire Poacher" Numbers Station. Some really terrific (and pretty fucking spooky-sounding!) archive recordings, featuring a guest-appearance from Akin Fernandez, curator of "The Conet Project".
Jeez: I remember sending an Orchestra of Doom demo to Akin back in the mid-90s.
He faxed us back but didn't bite lol.
Also remember hearing these on the radio when I was a kid back in the 60s and being completely baffled - weird glockenspiel chimes or an odd musical fanfare followed by streams of numbers or repeated words in a foreign language thru a smear of static. Still makes me kinda shiver.
