This orchestral piece was originally composed by Dario Marianelli for the 2007 movie Atonement. It was part of the score that won the 2007 Oscar for Best Original Music.
British rock guitarist Jeff Beck recorded the song for his 2010 album, Emotion & Commotion. He said to Billboard magazine: "The emotion of playing, say, 'Elegy For Dunkirk' is in some ways more intense and more gut-wrenching than playing the blues, 'cause those composers knew how to get you. The simplicity and just poring yourself into those phrasings is not dissimilar from blues at all. I'm sure people like Mahler and Holst and all the people that wrote such amazing music would agree with that. They want to get you to react."
