Thanks to the European copyright laws, after 50 years, you can re-release any record. Chances are that you won’t have the master tapes, but who cares? Taking it off an old LP can and does sound just fine.
So if you want to catch up on jazz, go to Real Gone Jazz, whether their own website, or through Amazon, or over the counter. 15 Sonny Rollins albums for less than £20!!!!! All Cecil Taylor’s early stuff before it went…er…challenging. Actually, the Cecil one is a must. Ahmad Jamal, Lee Konitz, Eric Dolphy, Freddie Hubbard etc etc.
Seriously, this stuff is a megabargain. The packaging is so-so, no track listings, but if you go to Amazon.com, you’ll often find a reviewer who has kindly done it for you, like this.
