Suresh,
I think this whole thirst for 'Recognition for our idol' - is born out of insecurity. I do not see any reason why people should be insecure,when IR is still musicially rich and talented. One should feel insecure, if he is running out of steam,musically. But he is not. He is going great guns. Then why do some people/fans feel so bothered about international recognition. It will come as by-product, if IR chooses to collaborate with artists firstly.
And as you said, his style of work is such that he might not be best in collaborating. This why i said it would be only 'interesting'.I only meant to sound curious about it and not that I would desperately want him to. If he collaborates,he would have make some compromises in his way of working,style,usage of thought etc and IR is known for sticking to his thought till the finish.So, he wouldnt be comfortable for sure. But then, thats exactly i am curious about - What would shape up, if he comes out of that comfort zone and collaborate with some good artist? I am plain curious! :)
