Anoushka began training on the sitar with her father Ravi at the age of seven. As part of her training, she began accompanying him on the tanpura at his performances from the age of ten, soaking up the music and becoming acclimatised to the stage. Anoushka gave her first public sitar performance on 27 February 1995 at the age of 13, at Siri Fort in New Delhi as part of her father’s 75th birthday celebration concert. For this solo debut, she was accompanied by tabla maestro Zakir Hussain. Her first experience in the recording studio came that same year when Angel Records released a special four-CD box set called In Celebration, to mark her father’s birthday. By the age of fourteen, she was accompanying her father at concerts around the world. At fifteen, she assisted her father on the landmark album Chants of India, produced by George Harrison. Under both their guidance, she was in charge of notation and eventually of conducting the performers who took part in the record. After this experience, the heads of Angel Records came to her parents' home to ask to sign her, and Anoushka signed her first exclusive recording contract with Angel Records (EMI) when she was sixteen.
