Matt:

Whoops, I should have put a few winking, laughing, smirking icons in my post.

If your 30 year period starts in 1959, then you're just too young to know anything (wink, chuckle).

BN was certainly a great development (started by a Brazilian pianist I believe - Antonio Carlos Brasileiro de Almeida something). Great compositions - the harmonies are different but great. One of my favourites is Dindi. I remember where I was when I heard the news of his death - listening to CBC radio while driving down Sahali Drive just past the school, in Kamloops, BC on the way to work - sad news.

I really don't think there is a definitive time period - in reality it's a continuum. But we can have fun BS-ing each other.
