this thread has appeared to me just as I've started to worry about all the music I'm missing. Some of this is a function of living in Shitsville; but it's also a matter of the expansion of music to the point that, eventually, to paraphrase Andy Warhol, everyone will record their 15 minutes of music. And the truth is that there is too much crap out there in every genre, jazz included, and I end up wasting my time on a lot of things which don't pan out. But it's necessary to make the effort.
there's an Isaac Babel story: "You Must Know Everything." I tend to agree.
I need a few years off and/or a subsidy to pursue a lot of it; won't happen, so I try to narrow the field and look for inspiration where I can find it.
