In a nutshell, I want to listen to, learn more about, appreciate, and engage in (i.e., go to live performances of) Jazz, without looking like a completely poser. Like many, I've listened to Jazz, but more as interior backdrop music. Does anyone out there have any CD/performer/book recommendations, or can point to a decent site that has good basic knowledge? In particular I want to know more about leading present day performers and good lives to attend. My goal isn't to learn the intricacies of musicality, improvisation, etc., but to grasp the greater landscape of important jazz works, artists, and more importantly WHY they were/are important. Any help would be much appreciated..
