Rahman and Michael Bolton in harmony

Oscar-winning Indian composer A.R. Rahman's song Sajna from Couples Retreat features in a new avatar in Grammy award-winner Michael Bolton's latest album Gems - The Duets Collection.

"When I first met Michael, we got to talking about music, philosophy, the universe, and many things that we had in common. I wanted Michael to do a bit of singing that he's never done before, without compromising on his musicality," Rahman said.

The album also includes musical collaborations with American band Rascal Flatts and Seal.

"It was an incredibly rewarding experience recording this album. The opportunity to work with legendary talent like David Foster, Dan Huff, A.R. Rahman and some of the absolute greatest singers and recording artists in the entire world was inspiring. I can't wait to share the special music we all created with the world," said Bolton.
