Nisi Dominus in G Minor, RV 608: IV. Cum Dederit

I have watched several times Simon Schama's Power of Art, which is as much a masterpiece as paintings that he deals with.  In particular, I am very impressed by a background music used in David episode.  His DVD did not leave any information about background musics.  So, I googled and found that so many people had the same curiosity as I have.  That is "Nisi Dominus in G Minor, RV 608: IV. Cum Dederit".  I put the link to the piece in Youtube here.
