Actually there has been a bunch of jazz, just seemed like time to address the "classics". All the Pat, Johnnie Mac, Al D, Jaco, Chick, RTF, Weather Report, and yes, even the Allman Bros. (#^&#^&#^&#^&ie said it, and I agree, they are a jazz band) it's all jazz, just different forms of Jazz.
So I added some BeBop, some Cool, and Monk (he is to his own music), just the straight ahead stuff versus the "fusion" kind. It's all good. Some just better than others depending on your taste or mood (my case it's just a mood thing cause I like it all).
and so some more
Duke (small group)
and full orchestra
