Brandenburg Concerto No.5 in D major BWV.1050 Johann Sebastian Bach
Bold, electronic - with a hint of Édith Piaf, Ennio Morricone and The Smiths - that's Hans Zimmer's score for this mind-bending movie.
After scoring Batman Begins and The Dark Knight, Hans Zimmer collaborated again with director Christopher Nolan for this 2010 futuristic thriller.
Before embarking on the score, Zimmer was told to let his imagination run wild. So, to inspire himself, the composer read Gödel, Escher, Bach: An Eternal Golden Braid by Douglas Hofstadter because, he said, it combined 'the idea of playfulness in mathematics and playfulness in music'.
What emerged was a densely constructed, imaginative, electronic sound world. At one point, while working on the score, Zimmer incorporated a guitar sound reminiscent of the music of Ennio Morricone and brought in Johnny Marr, former guitarist of The Smiths, to play the parts.
Édith Piaf's song, 'Non, je ne regrette rien" which appears in the film is also integrated into Zimmer's score. The film's iconic brass instrument fanfare even resembles a slowed-down version of the song.
