Ok, so I'm ready to go all in with Django, the legendary Gypsy jazz guitarist. But there's a problem: looking at Amazon, there seems to be several different multi-disc sets, that seem to overlap with each other. They all appear to be put out by one label JSP. I have a couple other things JFS put out, so I know they're reputable, but I can't figure out which sets I should get. Some seem to have been released circa 2002, while others look to have come out circa 2009-2012. Anyone conversant in this matter enough to untangle all this?
