Who is the musicians "The Silent Partner"?

There is this musician called Silent Partner who created non copyright music that is part of some YouTube videos. That normal and fine but one thing is bugging me, what is their history?

I tried to search but I find no leads at least in the Internet. Kevin Macleod, similar to SP, had a history but SP have no known history. People don’t even ask it in the Internet. They have prescience in YouTube and Soundcloud but no known past. So what is this mysterious history of the Silent Partner?
