white noise - an electric storm
delia derbyshire - unreleased tapes (bbc link)
white noise: late sixties rogue psychedelic-electronic mind-melter, holy grail for avant-weirdo obsessives. the first side keeps to a restrained pop framework, I guess if you consider sound-effect orgy recordings to be pop, while the second grows a beard and gets highly nasty, depicting the inner world of the spectral undead ("Visitations") and then go into a no-holds-barred abyssal freakout called "The Black Mass: An Electric Storm in Hell." There's later white noise records but they're basically solo Vorhaus albums. "An Electric Storm" is an unparalleled cannonball of whiplash studio effects and lysergic lasers.
delia derbyshire: hicks sent this link, to a post about a batch of unreleased tapes recorded by derbyshire. Today if you are a male guitar player you can impossibly fantasize about nico, if you are a laptop dork you prefer delia. She worked at the BBC Radiophonic Workshop and was a groundbreaker in electronic sound experimentation, her claim to fame being the recording of the Dr. Who theme. The tapes at this BBC link are nuts. Orbital's Hartnoll rightly observes that one of them could be coming out on Warp records next week. Delia did a bunch of sound manipulation on "an electric storm" as well, which explains alot. It makes playing with ableton live seem like monkeyshines by comparison.
