Next time when you are in search of the creator of a track, use Shazam! An app for smartphone that will recognise many song and tracks.

That said, in the same genre of the track you shared (which I like a lot to be honest), listen to the father of these type of tracks, Simeon ten Holt who composed in the '70 Canto Ostinato. For classical instrument, but you hear the resemblance?
