hi ASJ,
I am sorry, but I have to disagree about the comparison to Nusrat. Raja is very good, and is strong in many styles. His "Haaji Ali" was superb in its own way, but it takes a very special talent to catch Nusrat's style, and I think Raja does not quite make it.
Mussarat Abbas, on the other hand, is a very good candidate for the successor's job. My opinion.
