KS Chithra and AR Rahman have produced many iconic songs across languages, and it is a partnership that has endured for over 30 years, starting with Roja, Rahman's debut as a composer. In a recent interview, Chithra reminisced about the time she first came across the prodigious talent that is Rahman. Speaking to O2 India, Chithra said, "I saw him while singing for Ilaiyaraaja sir. He was such a small boy, a child. In fact, I was really shocked to see such a person play music."

In a surprising revelation, Chithra said that she did not know at the time that he was composer RK Sekhar's son, Dilip Kumar.

On the topic of collaborating with Rahman, Chithra said that it gives her plenty of creative freedom unlike other composers. "I wouldn’t know which version of my song would have made it to the final cut," said the singer, who is often described as the "Nightingale of Kerala."

Rahman's immense contributions as a musician often means that his ability as a singer tends to go under the radar a little bit, partly because he composes his own songs. His voice often lends itself nicely to soulful tracks, such as 'Tere Bina' and 'Ay Hairathe' from Guru, for instance. But Chithra is quick to acknowledge Rahman's singing prowess as well. "You know, some songs sound nice only if he sings them," she said, citing 'Mustafa Mustafa' from Kadhalan and 'Khwaja Mere Khwaja' from Jodha Akbar as examples.

The greater emphasis on Rahman the composer than the singer probably has to do with the fact that he often priorities other, more suitable singers for his compositions. Speaking about this quality of the legend, Chithra said, "He respects all artistes, singers, and musicians. He makes sure there is recognition for everyone’s work."
