Part of Mozart's Requiem - 'Kyrie'.
There can't be a God can there? If there is one he'd have to be some bloody wonder if he'd 'forgive' the bastards that KNOWINGLY make their livings and get their power from KILLING INNOCENT CHILDREN.
ADMIN EDITING - The music is by who is most often considered THE biggest musical genius the world has ever known, Wolfgang Amadeus Mozart, but the way a composer's music is interpreted after his death depends a great deal on the conductor, the grand maestro, and that sweet gentleman in the video above was probably also one of the best ever at directing an orchestra and/or choir to intepret a composer's music to its best advantage. The grand maestro above is Hungarian born Sir Georg Solti. He died in 1997.
