It's odd that there's a kerfuffle about this one when nobody made a fuss about say Goldmine's "For Millionaire's Only" which were 20 super-rare, hard to find tracks many of which weren't licensed from the correct owner.
Kent has just done a similar re-issue of the Antellects and the Ravins and I considered what damage it might do to the scene. They have both been around ten to twenty years now, there are enough copies of the Antellects to make it a very well known record to anyone on the scene over the past few years. A vinyl reissue makes it available to collectors who can't spend £thousands and will only get played at non-OVO venues and won't affect the price much at all. The Ravins took more pondering as I know Andy Dyson's been playing it over the last couple of years, and it's been so rare that nobody else has been able to copy him. In this case I doubt if the record would be able to get much bigger on its current schedule so collectors can buy it and play it at home or local soul nights (or in Europe, where the scene's not quite so fastidious), thereby spreading the music; and if Andy does play it out elsewhere most people will know it's the real Mccoy and pop up for a peek.
In both cases the direct families of the label owners will receive royalties. It's doubtful that those will filter down to members of the groups as they are so obscure and people have been tracking them unsuccessfully for years. If you come across a stray Ravin or Antellect please let me know.
