Hello everyone, I hope you're having a nice day.

I'm currently looking to identify a bunch of music from 80s, that could come from library music (I'm a regular user of WatZatSong for that objective).
One of the music that has been identified is this music called "
Dramatic Mountain Tension" (
https://www.youtube.com/watch?v=ZcSfarWnilQ).
The problem is that
I can't find any information or presence regarding this track...

All the infos I find points to inexistant labels (SINETONE AMR, Smith & Co.).
I have proof that
this music was existant before 1988; it can't have been released in 2016. In order to continue my searching, I have to find more informations!
I call to all the library music nerds that you are for help!

Listening to this tune, could you give me some infos, even thins?
Thank you very much in advance!
