Ok, here are my few observations on the box and its content. I am supporting myself with mentioned Bootledz site, adding commentaries from UU site also...
I think the idea of including all five shows in one big package isn't as bad as it might looked, even if the price is really big - I paid more than $400 for my copy! They designed the box in a really luxury way, and each of shows is released in individual hard glossy gatefold sleeve. The concept of issuing two versions for each of date may be disputable for some of us; however, I found a completely new ways of enjoying Melbourne, Auckland and Brisbane shows presented with alternate edits/mixes.
Now let's explore a bit each of dates included.
The Adelaide tape sounds as good as few previous titles, incl. EVSD "Deep Downunder". The big plus is fact that this time they didn't cut anything from tape as they did with their previous title (and for those, who are really keen to listen to this show in an edited form, version B is included, where all bad cuts and speed ups are removed in a really fashionable way). Similar to other reviewers, I had a feeling that this time tape sounds a bit more brighter, freshier. It could be a case of some soft equalizing but it also might be a fact they used real master and did a fresh transfer.
Melbourne show is a big treat to me. Composed from many different tape sources, we have two versions sourced from (mostly) different recordings. Version A sounds much better and version B shows so called "vinyl" source. I read on Bootledz that they missed some parts of actual tape sources and replaced them with alternate edits but I cannot verify it if this is true or not since my only previous release for this date was 7CD box titled "Thunder Down Under" (sic!) and released billions years ago by Japanese label Equinox. For sure this new version is much more complete and better sounding.
For me a big surprise is Auckland show, presented also in two different versions. Probably we all know famous excellent sounding tape that have surfaced on many bootlegs and low gen copies torrented here and there but having possibility of listening a complete show, combined from two recorders, making this date as my personal winner.
Sydney is probably the lowest point of this release, adding nothing but edited/smoothly prepared version on edit B but it's still good to have this date in the box. I heard that there are some copies containing unprocessed transfer of longer Sydney tape but I didn't feel any of EQ up here so I am leaving this chapter to much advanced trainspotters.
Brisbane date is again a very interesting piece of music and worth addition to the set. Composed from two tape sources, this show is finally presented in its full glory and again it's a big improvement over Equinox release. I read that speed issues that plagued both tapes are now repaired and indeed, this is a very smooth version of this show. The sound isn't excellent but still much more acceptable than Equinox and torrented versions of fan made releases that have spreaded over the years on various trackers.
Overall, the only negative aspects are the price (it might costs me less) and problems with second disc of version A for Melbourne, where they did Rock and Roll after Whole Lotta Love (probably they just tracked this disc incorrectly, giving individual track indexes erroneously). My copy arrived with replacement disc for Sydney so I cannot complain on this fact.
My rate is 8/9 for 10 scale and it's good to have all Aussie shows in their definitive versions in one package.
