Boy, you aren't kidding. I can't remember a year like this in many a year.
I'm tempted to say 1978-81 but at least then there were major new releases by Miles ('Circle In The Round', 'Water Babies' etc), some new Blue Note LP issues from the vaults (Rainbow Series) and Pablo was putting stuff out with gusto, like there was no tomorrow. And King and Toshiba in Japan were in their Blue Note/Pac Jazz reissue element..
Having said that, there's some cracking obscurities being miraculously re-issued at the mo' (ie. Kenny Wheeler 'Windmill Tilter').
