Our best guess so far is that Workingman's and American Beauty, at least, have not been remastered by the same engineer again and will be simply coloured versions of the standard Rhino reissues from 2011. Seems
Europe '72 had the same treatment at the same time. I've seen all three of those in almost every record store back in the before times. Not sure about Live/Dead. My best guess for the rest, that were remastered by Bellman for this set, is that they'll be issued separately shortly afterward for half the price.
