When Richard Clayderman and Rahul Sharma put their musical notes together, it turns out to be more than just a jugalbandi. The French pianist and santoor maestro, who marked their maiden collaboration 17 years ago, have proved time and again that music has no boundaries. The diverse instruments of piano and santoor transform into a source of magic and open a world of harmonies, melodies and emotions. They did it again with their special concert in Chennai last night. Having performed in Mumbai on numerous occasions, the senior musician, Richard, describes the city as exotic. “Mumbai is quite exotic for a French person. Such crazy traffic makes me dizzy sometimes,” he wrote, adding, “I wish I could perform more often in India, but my concert schedule is quite intense.” Rahul, on the other hand, enlightens us on his experience of making music with the veteran pianist and his probable return to composing for films.
