Q: I fell in love with Brasilian jazz my first trip to Rio. I've been there many times and was always amazed, visiting the little clubs, listening to a lot of great players. I don't remember how I found this guy, but, understanding music 'from the heart', Leo understands, and plays it that way. In my view, he is one of the most sensitive sax players I've ever heard - check out #3 on Black Pearls, you'll see what I mean..... I think it would be a great project for Leo to hook up with Bob James and Fourplay, and let Leo play, I mean feature him, write and produce songs that bring out his talent, give him lots of freedom. I rated this 4 stars, simply because of a couple of songs I skip pver, but all in all, it's great listening. And as a bassplayer, I've spent hours playing along with him.
A:
Positive
