Rok, every thing is sliced up in time; when you look at rings on a sawed off tree trunk, that tells you it's best years. I'm of the impression our favorite jazz is related to our best years. I believe our declining love for music as it becomes more current is an indication of our age, more so than the quality of the music.
Since we can not look at ourselves from the outside in, it's impossible for an individual to judge himself.
Today has been the best in a long time in regard to "new" music from the same time era. It's quite apparent that so much "jazz" came out at one time, that we could not have even known about it, much less bought it. I've said time and again that our present knowledge of this music is a result of current PC communications; I know I'm really enjoying it, and a side benefit is friends you don't have to feed or buy liquor for.
Enjoy the music.
