As much as Clear Channel might like you to think, jazz isn't the stuff they play on that Wave station at the end of the FM dial, which has the humanity produced out of it. Nah, that stuff can't be real jazz because it doesn't swing. Pop drumming and a soprano sax doesn't equal jazz.
Real jazz is performance music, usually put on by a small ensemble of four to ten players. The drummer doesn't play the obvious, patronizing beats you hear in pop music. Instead, he plays on the "two-four" pocket, following the tonal instruments as if he himself were a part of the melody. That's real jazz.

And you'll have a chance, tonight in fact, to hear some real jazz. Cleveland's annual Tri-C jazz fest will be in full swing, offering a mix of trios, quartets, and jazz revolutionaries, including the infamous Bela Fleck and the Flecktones.  These guys combine bluegrass and jazz in an experimental exploration that isn't all that experimental any more, but is still a blast to hear.  For the cost of a trip to Playhouse Square and a ticket, you'll get to hear Bela live and in the flesh, but you'll also get to hear his amazing bass player, Victor Wooten.  Now go check it out!
