Rajesh, on seeing your post I googled "Carnatic Omaha, NE" and was pleasantly surprised to find a thriving carnatic music organization there. The whole setup appears relatively new. They seem to have the infrastructure to host a good concert and a decent sized crowd can be seen at the events that are held at the Hindu temple there.
Pl see:

I noticed concerts by the Lalgudi Siblings with Patri (2009) and Delhi Sundarrajan vocal (2010).
I wish the organization continued success.
And best wishes to TMK and party for their concert tour. Look forward to hearing them in Toronto in a couple of weeks. No offense to Sri Arun Prakash, but I wish Sri Trichy Sankaran would play with TMK/RKSK atleast for this local concert

But the maestro will be accompanying Papanasam Ashok Ramani instead.
