Hey guys!

I watched this vid on yt and came accross some awesome orchestral stuff..

listen here

I know it says in the description that its been written for this video.. but it sounds so familiar to me and known even if Im not that much into this orchestral stuff

anyone here on the 4 who has any idea if this is legit and unknown piece of orchestral play or is the music from somewhere else? if so, do you know the name of the "song"?
