..every track sounds terrifying, as if it had been recorded in a 1930,s mental institution by the most dangerous man in there..and he,s coming for you!!

I remember hearing OMD's Maid of Orleans in 1982 and thinking it sounded brilliantly weird, right up until the 25 second mark when the "real song" starts:

Mind you, just a couple of years before, Laurie Anderson got to No 2 in the charts with this: goodness knows how

But if it's just "weird" you're after, then there's a vast landscape to choose from. My personal favourite is Steven Stapleton, aka Nurse With Wound. Here's something of his ("Strange Play Of The Mouth") which is slightly more like a song than much of NWW's other stuff:

Lizard People. Not to be confused with the talkie bits that seem to be compulsory on every Moody Blues LP to give the drummer some royalties.

Madonna's voice sounds lovely here.

There really is only one contender. This is one of her more accessible and poppy moments (and also picked because plenty of her videos are NSFW)

(Diamanda Galas and John Paul Jones - Skotoseme)

Just caught one of bbc 4's endless repeats of Totp and was stunned by Mr Big's 'Step back inside me Romeo she said. Step back inside me take me to your bed...'

Which ever way you look at it it's peculiar.
