I was initially going to just give this thread a quick scan and then move on, but I read the linked article and...
I'm now somewhat confused!
You see I own the Columbia/Legacy SACD (CS 65122) of The Dave Brubeck Quartet's Time Out.
I'm looking at the liner notes and they say that the 5.1 surround mix was mixed and mastered by Mark Wilder "10/3-10/4/2001" and that the SACD stereo mix was mixed and mastered again by Mark Wilder (I'm assuming on or about those dates as well - since it's not specifically stated.)
The linked article is dated 2013 and the whole article gives the impression (likely on purpose) that there was a lot of fixing-up done for this new 4 disc reissue.
They say that Wilder was responsible for the "new" mix.
So, to me, either Wilder was called in to fix his work of twelve years prior, or they're pawning off twelve year old re-mix and masters as hot off the press in time for the 4 disc reissue.
Those were my thoughts until I read the last lines of the linked article. It turns out (at least according to the parenthetical footnote at the bottom of the third page) that the whole article "is a re-issue of an article originally written for the July, 1994 issue of Audio magazine."
This means that they were talking about Wilder remixing and remastering from the original tapes (which were recorded in 1959) some time before 1994. Yet the SACD liner notes clearly say that he did so (again?) in 2001. So the 4 disc reissue must have been also before 1994. And the 2001 SACD came later.
But that still raises the question: why did Mark Wilder have to re-do the remix and remaster that the article talks about, for the SACD release in 2001?
Or does the lack of a date for the stereo remix and remaster by Mark Wilder in the SACD liner notes mean that they simply dusted off what he'd done prior to 1994 on the stereo version, and that they brought him in years later to tackle the 5.1 remix and remaster? If so, why not say so, since the SACD liner notes, by calling it the "SACD Stereo Mix" (my emphasis) they seem to be saying that it's special to that issue (as opposed to just dusting off what they'd sold previously.)
