I know this Opera very well, I have found it gripping and rich with musical ideas, ever since I discovered it when I was a student and had the good fortune of seeing a mesmerising live performance by the WNO in Bristol in the late 80s. I have seen various other performances on DVD and heard a few recordings on CD (my favourite is still Solti's with Nilsson).
I bought this new Chandos set for the simple reason that I do like to follow an opera and understand majority of libretto while I listen. As my german vocabulary is very basic, I have been buying a few of the Chandos releases of the translations into English of german opera.
So, the diction in excellent and therefore for that reason alone, recommendation is forthcoming. The cast is competent, even if not brilliant in terms of characterisation when compared to a lot of other recordings (albeit all in german), they are pitch perfect. The main thing for me that took one "star" away from the review score, is that Salome's casting does not work well for the first half, even if very good in second half. A good performance of the part, in my opinion, needs to start more sweetly in tone, and a certain amount of curiosity in the character, and then as the plot progresses, we need to (see) and hear Salome's descent into uncontrolled combination of scorned anger and vengeful lust. We get the latter in this recording, but at the start the same tone quality is also employed here and makes Salome end up sounding much older and "shouty" than she is in the story. Se sounds angry and shrill from the start, and I was starting to get annoyed until after her encounter with Jokannaan when the mood darkens, at which point the same tone quality becomes fitting of the character in the second half, especially the deranged final soliloquies.
The characters that stand out for great singing are Narraboth, Jokannan and Herod.
