My own preferred format:
Standard version
CD1: original album stereo/mono
CD2: outtakes, demos
CD3a (and 3b if necessary): contemporaneous complete live show from that era
Deluxe:
CD1: original album stereo/mono
CD2: outtakes, demos
CD3a (& 3b, 3c 3d, etc): several contemporaneous complete live shows from that era
CD4 & 5 (or however many are necessary): session highlights
LP: remastered audiophile of original LP sides, with bonus track(s) where feasible
Book: in a readable format – ie, not something so over-sized that it's impractical to read on the bus, in bed or on the bog – recounting the sessions, the lyrics, reproducing contemporaneous magazine/music paper interviews and features, Craig's session details, and the narrative tale of what the band was at at that time in their history: essentially each would be a stand-alone chapter recounting that era of the band. From a marketing point of view, to get the complete story you'd have to buy each box.
Other: repro in-store display piece for that album, with authentic bag of crisps/chips
This plan will change in about five minutes, but I'd be wetting myself with anticipation over this for the next four minutes.
You would only get 2 live shows (1960s) or 1 show (1970s onwards) on 1 Disc. It's only 80 Minutes!
Aye, in fact as a recent boot demonstrated, two or three early shows would fit on one Cd but some early/mid-70s shows would need two CDs easy. Hopefully in many instances they'd pick UK performances as they tend to be longer and go deeper into the catalogue. Length though isn't the issue, it's the context they offer to the studio album they accompany/support.
