MUMBAI: Every singer dreams of working with the Mozart of Madras but, there are only a few who have begun their singing career with him. Shashwat Singh is one such lucky man.

Singh, who has taken formal training in western classical from Rahman's KM Music Conservatory in Chennai, made his Bollywood debut with Rahman's 'Wat Wat Wat'. The song was a part of Ranbir Kapoor and Deepika Padukone starrer 'Tamasha'. Prior to this, he worked with Rahman for his band NAFS and for his initiative with Shekhar Kapoor, Qyuki.

The singer now lends his voice to 'Sarsariya' from 'Mohenjo Daro'. The song features Hrithik Roshan and Pooja Hegde.

"I keep singing for Rahman sir once in a while and at times one of those songs get finalised," stated Singh, who was surprised to learn about his voice being selected for 'Sarsariya'. "I went to Chennai a few days ago to record another song when Rahman Sir broke the news to me."

The singer was extremely happy to have learnt about his voice being retained for 'Sarsariya' for he really wanted the song. "When you walk into a recording studio you're always blank. You do not know the tune or the way you would be singing the song. 45 minutes later you get the hang of it and you know that the tune will be liked by all. I simply loved the melody. In fact, Sashaa (Tirupati) was there in the studio when we recorded it and I mentioned to her that I badly needed this song," confessed Singh who has sung songs in Tamil, Telegu, and Malayalam.

Singh who has given his hundred per cent to the track believes that each song has its own destiny, but he always expects the best.

The singer is now looking forward to his UK-US tour with Arijit Singh. He is also wanting to explore singing opportunities with Bollywood music composers Sachin-Jigar and Pritam.

Singh also continues to work on his independent songs. He has earlier sung songs like 'Bas Tanha', Bavala', 'Mata Saraswati' and 'Jaane Kaise'. His last song was a collaboration with Shankar Tucker.
