OK, here's a review from someone who's actually heard the release.
CD1 is the original album remastered. And what an excellent job has been done. I have the original 1991 Rykodisc era Sound+Vision release and this tops even that. Not only are all the instruments clear as a bell, the bass is more prominent, which really brings the music alive.
CD2 and 3 are Bowie's March 1976 Nassau Coliseum concert. Long term fans have long cherished bootlegs of this night - the band is far less cabaret than Bowie's 1974 outing and less cold and brittle than the instrumental-dominated 1978 Stage incarnation.
The concert has a good mix of Station to Station tracks - of which the title track, Stay and Word on a Wing are masterful - and older hits. Some of the recordings are a little ropey - Life on Mars and Five Years are (superior) bootleg quality and the mix on the 2nd half of the concert is somewhat unbalanced - cymbals dominate, you can only hear one guitar for a lot of the time, the piano is very quiet and the bass just a low rumbling. Whilst Jean Genie and TVC15 suffer most from this - both sound thin and even weedy during choruses and solos - Changes, Diamond Dogs and Queen Bitch are by contrast hugely entertaining - and Panic in Detroit is positively furious.
The packaging is great. A Cameron Crewe essay puts the album in context, followed by a detailed chronology of the preparation and execution of the album. Three CD sized postcards complete the box.
Station to Station has always been a masterpiece - a satisfying and consistent yet diverse collection of powerfully realised signature tunes. This set puts Bowie's mid-70s journey into context, gives us his most satisfying live album to date and reinforces his mastery of both art and entertainment.
