As part of the BBC's Sound of Cinema Season, Tom Service concludes his series of discussions with film directors and composers. Australian director Baz Luhrmann shot to fame in 1992 with Strictly Ballroom and was nominated in 2003 for seven Tony awards for his Broadway production of La Boheme. He's best known however for his bright and brash films Romeo and Juliet, Moulin Rouge, and The Great Gatsby which was released earlier this year. On all three he has worked with Glasgow based composer Craig Armstrong who studied with Cornelius Cardew and began his career as in-house composer at the city's Tron Theatre. Baz and Craig explain how their creative relationship works and reflect on the role of music in Baz's films. #BBCSoundofCinema.
