I have one (only one - it's enough) CD from American psycho-acoustic pioneer Maryanne Amacher (died in 2009). She developed a technique where sound waves interact with your brain to produce truly weird and sometimes extremely unpleasant distortion effects inside your head.
Headphones on - and not for those of a sensitive disposition.
Maryanne Amacher: Living sound (1980)
Any more seriously strange recordings out there ?
