I already had all of the albums; The Sicilian Defence is the only new material, but this is the only way to get it.
I was sort of surprised to find that two of the cardboard CD cases had gatefolds.

I haven't actually listened to the box set yet, partially because I haven't really had the time and partially because I don't really know what to do with some of the albums. Like I mentioned above, I already had copies of all the albums (save The Sicilian Defence). Of the copies I already had, about half are just the album as it was originally released, and the other half have bonus tracks in addition to the original album. The albums in The Complete Albums Collection are only the albums, no bonus tracks (adding bonus tracks to the albums is probably the only thing that could have improved the box set). When I rip the CDs from The Complete Albums Collection to my computer, I want to distinguish them from the albums I already had, and I don't know the best way to do that. I'll probably just end up adding "The Complete Albums Collection Disc x" before each album title.
