Expanding this topic a little, can folks here explain this to me? I frequently see posts by people who already have all the material in a newly-issued box set, but still buy the box set. I'm not being judgmental, just curious. Since it's something I wouldn't do, I don't quite understand it.
As a reviewer, I didn't pony up as much dough for it as I would have otherwise (would gladly have paid full price for it if I "needed" to). However, for me, it was a chance to evaluate the material as a whole rather than as individual releases heard and experienced over time. Though to somewhat different ends, I think the Mosaic consumer who has the material already might want to experience it differently, in addition to the collecting impulse. I'm sure there will be disagreement over this, but it's a thought.
Braxton's notes would have been great to have as well, though he's moved on in terms of his process from where he was in the mid- to late-70s.
