NEW DELHI: Academy Award winner AR Rahman is all praises for 13-year old Lydian Nadhaswaram. The teenager won a million dollars for his performance on American reality show 'The World's Best'. Lydian said, “It was really good performing in a huge international platform. I practiced a lot for the competition.” The young prodigy also made his debut on 'The Ellen Show'. The “piano prodigy” is also a student of AR Rahman's Chennai-based KM Music Conservatory. However, Rahman has different hopes for the young one, who he called an “ambassador” for Chennai and India. Rahman said, “I want him to become like the Lang Lang for India.” He was referring to the Chinese pianist, adding that Oscar was not an ultimate goal.
