Golden age of vinyl recordings?

Current Berlin rent is quite low though rising, yet I don't hear anything happening there except techno clubs. London might still have what it used to have. Just move one hour from the city and rent can be okay, just like New York. Not that convenient but not bad. 
Obscure bands, great concerts by well-known artists recorded but never released..

For Jazz, there are different sorts. I am not a Jazz expert, so please do not burn me for my failures to describe the periods)  The fist big one is the era of the Big Band. Spectacular bands playing great music. 30's and 40's era. Plenty of repackaging of that material so pretty easy to find. Then the rise of BeBop. Late 40's through 50's Really the Whole experience of many folks Jazz are all in the 1950's. Continued through the 60's. Then it changed.. trying to move forward, it just went where many refuse to go along. Some Jazz stayed the same and calcified. Some went so far off the known Universe as to not be Jazz at all.                

When I bought my Klipsch Heresy III speakers last year there was a "free album" offer sticker on the boxes. One per speaker...so I went to the Klipsch site and wound up with 2 10" 33rpm mono albums, one of early Monk, and a Miles Davis thing...AMAZING quality things that sound so good in all ways (even with my stereo phono cartridge) that it blew my little mind. If anybody needs to see where Jazz went, listen to people like Vijay Iyer and Craig Taborn, and many many more current geniuses...it's alive and well.
