When Stokowski began to make Phase 4 recordings for Decca in 1964, he was already 82, but he hadn't lost his energy or his tendency to shape music in outlandish ways. I mostly love him, but this box set duplicates recordings that can be found on the Cala label, which has been releasing everything Stokowski in the world. You can slso hunt down Decca single CDs if you go to the used market.
I mention that because this sizable box set, Vol. 2 in the Original Masters series devoted to Stikowski, contains some forgettable performances, in particular the rhythmically slack Beethoven Sym. 5 and 7, the over-highlighted Schubert 'Unfinished,' and a live Brahms First that seems manic and forced much of the time. However, if you think of Stokowski having little to offer in the German classics, here is an exceptional Beethoven Ninth, one of the best things from his late career and wonderful in every way.
Decca knows that the crowd-pleasers are the gaudy, multi-miked Phase 4 versions of Scheherazade, as gaudily bombastic as you could imagine, and lots of Russian fare, including Stoki's signature synthesis from Boris Godunov. The 1812 Over., by the way, isn't over the top -- it needed to be. Finally, this German-Russian collection contains a thrilling disc of Wagner excerpts, much of it grossly over-miked, but at its core containing very impressive, vital interpretations.
In all, I'd select the Wagner, the Beethoven Ninth, and the legendary Scheherazade as the best things here. Buy them separately or take the plunge for the whole box, your choice.
