I found the blogs from Amitava and Sudipta quite interesting. I preferred to skip Raghab's show @ Kallol over Chandrabindoo, but heard him singing the following weekend @ NY.He performed very well inspite of the poor sound system. He sang a wide variety of songs from bengali folk,films, recent hindi hits etc, By and large the audience enjoyed his show. .

 I have more questions and few answers when talking about our Bengali entertainment scene in NJ. Some of my thoughts:
Catering to and satisfying a wide cross section of public is not an easy task. We need tolerance and acceptance of programs designed for a section of the populace different from which we may belong. Maybe Raghab could have entertained the Kallol audience better if he had known about the type of songs we would like. This applies to any performer for any show. 
We need ideas from all to enrich our entertainment scene and that includes our nextGen.
One of the reasons we could not get the  Bengali-NextGen( BNG) participate more wholeheartedly in our cultural events is because we are not receptive enough to listen to them. Have we tried enough to encourage them on topics of their interest? Why not provide them with a program slot to present their ideas?  For the past many years we have taken pride in always 'importing' cultural icons from Desh and presenting them,...its high time that we start presenting our home grown talent. This year's natak @ kallol Puja was a great example of how given an opportunity and guidance, the BNG can entertain us with quality presentations. Kudos to Sudipta and his team for leading the way.
I believe we will be better off having a policy of inclusion over exclusion. Some appreciation, tolerance and patience is called for from the audience. 
Culture is not about 'commodotizing' a product. There cannot be a perfect 'cultural product' to sell in a market. Culture is a way of life,a perception that has to be felt and experienced by those who are inclined towards that experience. I think the 'value' factor for entertainment cannot be weighed in terms of '$$$' terms only.
