Good Modern Jazz? - No such thing.
However, Kent records do a series called "Mod Jazz" ; this is "modern" (1963-69ish), but is very listenable (!), funky and even dance friendly.Unlike the arthouse beatnik racket that people pretend to like because it displays how "cultured" they are!. Sorry, a bit of a rant. Modern Jazz is hard work - don't do it!
The word may be an oxymoron but the sounds that I listen to of the tradiotionalists is the best jazz , in my opinion . If you are interested in beautiful, interesting ,meaningful music which stirs your emotions. listen to the music of those guys who defy categorization.'' If it sounds good it is good" DUKE ELLINGTON
