The coming 34-CD+1-DVD “Wilhelm Furtwängler – Complete Recordings on Deutsche Grammophon and Decca” box set is apparently modelled on the Japanese Das Vermächtnis von Wilhelm Furtwängler 34-CD box set released back in 1994.
The content is very similar, except that the new box set includes a Don Giovanni DVD, which is still available separately, and now with more information of the contents available, we can have a better understanding of how the new set compares with the earlier one.
The order of the recordings in both sets is very similar, because it is mostly chronological. The chronological order as stated by DG refers only to the grouping of recordings in the sequence of pre-war, wartime and post-war periods, and not to the chronological sequence of the recordings within each time period.
Given that the wartime recordings have been reissued in 2 small Collectors Edition box sets (471 2892-2 and 471 294-2) in 2001 after the initial ground-breaking 10-CD box set (427 773-2) released in 1989, and the DGG Recordings in the DG Originals series, it remains to be seen if there is any new remastering in this large box set.
