This one has been around before. Never solved. Originally featured on and extracted from a mixed comp made (and shared) by a spanish user that just wouldn't be kind enough to share the tracklist despite several requests.

I bet it's from the late 80s, most likely vinyl only. I hope someone can get this solved, I haven't been able.
Thanks for any help.
