o10, you were apparently quoting Redman, but I don't agree with "there are certain things like swing, that are crucial components of jazz". When a performance swings that can be enjoyable and even stimulating. But in my opinion that is not essential to being considered jazz. I've always used a measure of a sense of improvisation. That's one reason I enjoy solo or small group more than big band, there's more room for improvisation. Here's an example of something that doesn't "swing" but clearly has an expression of jazz in my perspective.

Others may agree or disagree, I don't mind.
