@curiousjim, I have been pulling out a bunch of Brazilian CDs I forgot I had. I'm now listening to Selma Reis and Maris Monte. I listened to Jorge Ben yesterday, but my wife was home and I couldn't blast it, the way I think it needed to be. The recordings were made live in an arena and need to fill the hall.
A question has arisen, though. I don't know if any of these are really jazz. They sound more like Brazilian popular music. I have many Brazilian (French, African, etc.) recordings whose genre I've never tried to distinguish. I love Angelique Kidjo, but I'm not sure I'd call it jazz. It doesn't really matter when I'm listening. I like what I like, but for this forum, it might matter?
@stuartk, I think you need to take a couple things into consideration about what you like now and what you don't. First of all, hearing music live is a very different experience. There have been a number of artists I haven't liked until I hear them live.
Then, our tastes change as we age. I think the reason I continue to listen to Tania Maria and Flora Purim is because they are jazz. A lot of the other music I have from Brazil is popular music. And quite frankly, I grew up with American popular music, have been more exposed to it, so I like it better. Even though I took some exotic tours when I was younger, I have returned to Paul Simon, The Band, etc., when it comes to popular music.
