At this stage I'm getting the calendar for the calendar itself (love those images), but probably as much for the great remastering! According to the website, they use the same process as for the "American Epic" remasters, and those truly sound "epic". These tracks become my "reference library" of the best possible sound for most of the recordings.
I'm one of the guys that does not mind hiss and crackles, and is totally against the auto-processed-to-death-stuff from the 90s, but loves the "best possible and painstakingly restored" sound that we first got with the Robert Johnson Centennial Collection and now with some of the more recent releases.
I still wish someone would treat the entire Son House Catalogue (especially the 1941-42 Lomax recordings) to this process, I'm sure there's a lot that can be improved compared to the commercial releases out there.
