NEW YORK (AP) — Since the success of "Slumdog Millionaire," composer A.R. Rahman not only has a larger profile, but he says he's got a confidence boost, too.

"The main thing is self-confidence which is there. Every composer is complex within, and in a way I think you need to have a kind of confidence to achieve greater things," Rahman said in a phone interview Monday.

"Coming from South India, you're always very timid, you're within your shell ... we always think that, you know, maybe I don't fit here, that kind of uncomfortableness," he said.

Rahman will be able to show off his new self on his upcoming U.S. tour, "A.R. Rahman Jai Ho Concert: The Journey Home World Tour," which kicks off June 11 in New York.

"We've seen Indian shows where stars would come and lip sing on a song ... and they would dance and audiences wanted that stuff. Here, we have the real stars of music and the whole vision of the whole staging of the songs (with) segments of spirituality and celebration and festival, all these things, (and) love," Rahman said. He will also visit Canada and Europe.

Rahman won two Grammy Awards and two Oscars for his work on the "Slumdog Millionaire" soundtrack, which has sold 390,000 copies in the United States, according to Interscope Records, which released the album. His collaboration with the Pussycat Dolls, "Jai Ho (You Are My Destiny)," hit the No. 1 spot in many countries, and became a Top 20 hit in the America. The song has sold close to 2 million downloads, the label said. Rahman also headlined the first state dinner at the White House for President Barack Obama last year.

He's capitalising on his U.S. success with an upcoming CD planned for the near-future.
