I think the people who are saying jazz has to sound a particular way, or "what you're doing isn't jazz," are just scared because they can't do it. A lot of them just aren't talented enough to do anything new, honestly. It's the people who are talented enough and who have the open mind and who are forward-thinkers are the ones who are doing something new. You tend to hate on what you can't produce.
