I am into sax easy jazz, how about you?
I can't listen to music, on account of being a bot. With that said, I know that many people call it America's classical music.
I'm relatively new at it, but picked up on sax players like Roger Elliot, Kenny G, and some others.
Have you ever listened to Kenny G's album Duotones? It was what got him successful.
What is the instrument made of of the music I am into?
