When a 23-year-old Asha Bhosle first met RD Burman in 1956, she was an experienced playback singer, and Burman the teenage son of a legendary composer. Ten years later, they would collaborate on their first film, Teesri Manzil, starting a creative and romantic partnership that revolutionised Hindi film music. Burman introduced elements of funk, jazz and garage rock into his sound, while Asha's voice – sexy and slightly cheeky – provided Bollywood with a daringly risqué element.
