Michael Berkeley meets Turner Prize-nominated conceptual artist and film-maker Sam Taylor-Wood, whose biopic "Nowhere Boy" traces the early life of John Lennon. Much of Taylor-Wood's work has been inspired by music, from opera to Bach, and her choices range from the opening of Gluck's opera "Orphee et Eurydice" the Kyrie from Mozart's Requiem and the opening of Beethoven's Ninth Symphony to an Indian raga, Nina Simone singing "Wild is the Wind", and film scores by Ry Cooder and Michael Nyman.
