Jazz is not Blues and Blues is not Jazz.......

How's this, Country Western, Rock and Roll, Blues and Jazz were ALL born in the USA. They are bound to cross a few boundaries.
Wrong country for being a purest, ay?

If you think about it, one was born from the another, or branched and taken from another. It's not like Opera, Dixieland jazz, Bali, or Bagpipes, crossing lines... Just sayin, more alike than not...

Whatjd, you have to be a little more specific, we seem to have too many different kind of "Blues's"; Delta Blues, country Blues, chicken little blues, Gumbo Blues, and I don't know what else; you see my point.

I'm 100% on your side because I have never liked "Delta Blues" and in no way should it be included with jazz.

However, here is where confusion arises; one of my favorite tunes is "Sandra's Blues"; I knew Sandra, and I remember when she got the Blues, it was because of that no count man she was foolin around with; but Sandra didn't like Blues she was strictly into jazz, the same as the artists who are playing this tune.

Maybe you could clarify that bit of confusion.

When it comes to music "Google" is out to lunch;

Overlap:

Anyone who doesn’t understand that had there been no blues there would be no Jazz, well.......

When it comes to music it's best to follow your heart, not your mind.  As fun and enlightening as analysis may be, don't let analysis get in the way of a good time.
