I've just remember Immediate Music they would be the most similar to this particular style. http://www.myspace.com/globusmusic (listen to the song titled 'Spiritus Kyhayyam' - http://www.immediatemusic.com/
cinematic orchestra or electronic orchestra (this particular video is more electronic)
similar artists would include Craig Armstrong, Rob Dougan, Harry Gregson Williams, and the aforementioned ES Posthumus.
