I've been looking for a song for three years, anyone know it?

I saw a tutorial on You Tube that featured a very unusual song. It was entirely instrumental...no lyrics. About three years ago, the guy who put up the video terminated his account and took all of his videos along with him. I haven't a clue what the name of the song was. It started out with electronic whooshes and whirs. Then it became a soft guitar song for about a minute or so. After a while, it sounded more like a rock song. Does this sound familiar to anyone? Sorry if I am being vague. If you would like me to elaborate some more just say so.
