Which version of Mozarts Requiem - Lacrimosa is this ?

[Kai-Andre]

A dear friend had sent me this video asking me the name of the song. It sounded like Mozart so sure enough after double checking on Midomi;
Requiem: Lacrimosa. Neville Marriner


Just to be totally sure I played the track again and noticed it was not the same at all ! How could this be ? So I played a different part of the video and checked on Midomi , this time the result being; Requiem KV.626 (Excerpts): Lacrimosa. Vienna boys' Choir


So 2 searches on the same song but different results.


Pay special attention to the trumpet(?) at 59-1:00. It sounds great ! But unfortunately leads me to believe this song has been remixed, edited etc.
