Artists that deserve box sets

It seems this Christmas we are being inundated by repackaging and box set treatments for old albums. Some of the remastering work has been terrific, but some of the packages appear to be simply exercises in greed. I was wondering what artists the Agon community believes to be worthy of the box set treatment. I am not talking about a greatist hits collection. I want unreleased tracks, live cuts,and alternative versions mixed in with the established tunes. In some cases I want to cull the selection down from huge cataloges of work. My candidates are: The Connells, William Clarke, Clarence Gatemouth Brown, Charles Brown,Widespread Panic, and Gene Harris.
