In all, between mono and poly rhythms, we have seen Raja progress through 17 stages. While most composers easily do 6 to 8 stages, going beyond that is a challenge. Today, most composers blame stories, scripts for their lack of experimentation. Nothing can be farther from truth. Raja has done his musical experiments in several non descript films that did not have the great stories or scripts. If a composer has the commitment towards innovation, he can find a way.
We can only hope that some Indian music composer in the future will attempt to surpass these 17 stages. Till that happens, we must thank that we are born at the time of the genius who set the bar.
