Check out PBS in the wee hours of the morning. You will catch some great jazz music/musicians fairly often. I have to say though that jazz seems to have a bigger following in Europe and Japan than it does in the US right now. Not that we don't have jazz lovers, but it seems that jazz is almost mainstream in other nations. Over here hip hop, alternative, and dance still reign supreme (gag). Maybe it's a reflection of our younger culture over here...I don't know.
It did encourage me though when a "metal head" friend of mine was complaining about mainstream rock stating that everything sounded the same. Just for kicks, I brought him some early Parker/Davis recordings expecting to get a disgusted look. Much to my surprise, he loved the music. Even more shocking was the fact that he went out and bought some Weather Report, and Jeff Coffin's "Bloom" after I introduced him to fusion jazz. Uhhh...possible future jazz revival? :? :? :? I sure hope so.
