I have spotted that a number of tracks fade bout which seems odd given the size of the boxset. Heavens alone knows how many discs would have been required to hold all the concerts in their entirety. Also, the start of some of the tracks seem very abrupt, presumably because they've cut the audience appreciation of the previous tune. All of which may be a product of AB's decision not to present the music as played on each night but to cut/paste from different nights and venues.
None of the above detracts in any significant way for me from what is a tremendous release overall.
