Hello Brian,
Nansady hasn't given class in Sangbarala very often during the last few years as far as I know.
I spent some time there with him in 2001.
Now it's all in CKY, but he might take some pupils to Sangbarala for a week or so sometimes. (Yes, he does! just found this:

What is more important to you, taking class in Sangbarala or taking class with Nansady?
Namory will give a class in the village this year and so will Solo, I think. Nansady will stay in CKY most of the time.
He's a great drummer and a great guy for sure!
Greetings,
Daniel
