A cryptic title simply to mark the (re)discovery of Haydn's 91 symphony (disc 1) in an interpretation which is a definitive if very creative reading of that composer in my humble opinion. The set is worth purchasing for this recording alone.
But there is more.
In more generalised terms, this boxed set offers a motley selection of recordings of Furtwangler and the Vienna Philarmonic, made all the more interesting because there is NO Beethoven NO Wagner and NO Brickner in this set -- i.e. all the usual suspects are absent from the list of composers. Which is marketing's way of attracting our attention -- it did attract mine, at least.
No Beethoven but instead we have Cherubini, Gluck, Weber, Mendelssohn, Liszt, Berlioz (very interesting)... and the crowning glory of this compilation: Mozart 40 and Haydn "Surprise".
The other reviewer has dwelt on the latter, so I will only add that this rendition has unusual tempi, and allowances and creativity with the written script -- all in the manner we would want to have from a great maestro: we want the great maestro to be a magician and, given a script, to create something new. And Furtwangler does so here.
However, the Mozart also merits some special mention: there is seemingly relaxed attitude in this performance recorded at towards the end of the war. Close listening seems to reveal a hidden intensity (the strings crescendo peaks...) that throughout permeates the symphony especially the 1st and last movements. Joviality seems to be replaced by speed and intensity -- an inquisitive look into the composition where the dialogue between violins and strings is more a heated conversation than a relaxed exchange. The third movement has a sense of finality to it and an undertone of tragedy at times. The fourth unleashes energy and strength -- and, speed!
Lots other goodies in that box not only for enthusiasts. Very thoroughly recommended to all!
