So I am sure you’ve all seen (heard) the “Brainstorm / Green Needle” stuff. Weird.
I can’t remember if I mentioned it previously, but back in the day we were similarly weirded out by a song that I hadn’t been able to locate - but just have.
One of our group of mates had this on vinyl. Someone else recorded it onto a cassette. Which then found its way into the 4-track being used for makin muzaks.
Some of you will be fully aware that cassettes have 4 tracks on them - left&right channels for each side of the tape. So if you put a cassette that has already been used into a four track - tracks 1&2 can be played back normally, tracks 3&4 come out in reverse.
Through this, some weird event lead us to a discovery. At the start of the song Insomniak, it states “Insomniac. I Must Sleep”. When played backwards this comes out as “Insomniac. I Must Sleep”
This was obviously intentional, and comments on the YouTube vid confirm that others have discovered this too, but it is freaky weirdsville nonetheless.
Download any of the many sound-reversing apps available and try for yourself. (You won’t want to go much past the intro anyway - the track has not aged well )
