Yes. A true legend. My father was (and still is) a huge fan of him. The very first songs (apart from Malayalam) that I remember enjoying during my childhood were from him. Then Rehman Sir came and I was listening to more of his music.
Once I started getting into serious listening, I began to appreciate Raaja Sir more. Though I am grateful to Rehman Sir for all the wonderful music he has given, at times I feel that his work is not as natural as Raaja Sir. Different composers, different styles and different technologies in music production. How i sincerely wish we had more good recordings of Raaja Sirs music.
