I do not think Ron is personally slighting anyone by certain tapes or cds no longer being available, it could just be dubbing more is no longer convenient (due to poor interest) or the master is hidden/lost. I've contacted him about various pure CDs being told they were no longer stocked. And honestly given the state of things, especially with Discogs can you blame him? Most of this stuff is available still at very reasonable prices and he's been forced to sell at lower prices on Discogs than on his own site.
I don't personally know Ron, but I assume like everyone participation ebbs and flows, hope he finds passion again soon in performing and releasing...RRR is one of the greats.
Are there even any "new" recycled tapes in the last few years?
