Leonard Slatkin Conducts the BBC Orchestra on September 15 2001 in honor of those who lost their lives a few days prior. Visuals from BBC's 'Last Night of the Proms' and ABC's 'Report from ground zero'. AUVIEX edit. (1.5 million YouTube views)Voted by BBC radio listeners in 2004 as the saddest piece of classical music ever. Incorporated as part of the soundtrack of the movies "The Elephant Man," "Platoon," and "Amelie."
I'll use this as an excuse to once again recommend "Gortoz a ran - J'attends" ("I await").
