The day may come when people no longer argue about jazz and they're all in agreement; I fear that day, because it will mean that we're a fossil.
It's always hard describing things that are vibrant, alive and evolving. Something that's dead and never changes is easy to define. The fact that it's hard to define jazz and people will debate its meaning is a positive thing. The London scene has music that some might argue isn't jazz — but the fact that that argument is taking place is the healthiest thing you can imagine. Same thing in the 1940s when people were saying Charlie Parker wasn't jazz. That was great for the music. The day may come when people no longer argue about jazz and they're all in agreement; I fear that day, because it will mean that we're a fossil.
