MUMBAI: AR Rahman is scaling one milestone after another. The ‘Mozart of Madras’ performed at the White House in front of President Barack Obama and Indian Prime Minister Manmohan Singh to mark the latter’s visit to the US. He sang two tracks — Jai Ho and Dreams on Fire — from his Oscar-winning movie Slumdog Millionaire. As part of an initiative by the government authorities, Rahman performed with Indian and western artistes to welcome Singh in the US. A source said, “It was an electrifying performance celebrating brotherhood between India and the US. Rahman set the mood for Singh’s three-day visit to the US.”
