It doesn't take long for even relatively casual students of Stonesology to realize that there is a hefty chunk of their back catalogue that has never been released. The reasons are many and various, including all kinds of contractual grief, an acrimonious split with a manager whose estate still has a stranglehold on the rights to the cream of their back catalogue and a weird kind of hubris which attaches itself to the band and dictates that they really don't wish to have to compete with their younger and infinitely groovier incarnations as they still have the occasional album to release or the occasional tour to contemplate, Keith's arthritis and Ronnie's ongoing dalliances with the demon drink notwithstanding.Read the whole thing at Cloud 109.
The fact that really amazing material is held under lock and key, while all that devoted fans can access through legitimate channels are pseudo rarites which in effect are nothing new just adds to the sense of frustration.
So the reasons why bands such as the Stones created such a long standing gap in the market are fairly plain to see but with all gaps in the market there are always entrepreneurs ready to satisfy these latent demands.
In the late sixties when there was still a genuine buzz of excitement around bands such as the Stones, there sprang up in America a generation of young guys that were not just into the music but were also enterprising enough to cater to the desires of collectors whose needs were not sufficiently sated by the corporate decision making (or lack of) of the sprawling and sluggish behemoth otherwise known as the music biz.
