The other Wagner/Muck disc is more important for your collection
Wagner: Parsifal (highlights) providing much from Bayreuth itself, and a chance to hear the special Parsifal cathedral bells (lost in the war) and superb conducting from Muck and S. Wagner, men with a special affinity for Wagner's last work. The great singers are also a must hear.
THIS CD packs quite a lot in. Preludes to the Dutchman, Tannhauser, Lohengrin (Act 3) and Tristan, the Funeral March and the Siegfried Idyll. Sound is very good for the time, and so has that special ambience that comes from really old records beautifully remastered for the Twenty-first century enthusiast. The orchestral contributions are stirring but not always error free and Muck's direction, though lively, isn't so extraordinary that one should say he eclipses his successors on EMI or elsewhere, all recorded in richer sound. The booklet points up Muck's connection to old Bayreuth and suggests a special authority in his conducting of Wagner matched since by Boult! I used to own the Boult Wagner album and, like Muck, The Parsifal prelude was wonderful but some others were less special (e.g. excerpts from the Ring).
I agree with my fellow reviewer about the Siegfried Idyll. It certainly is a very fine performance. I'll certainly hang on to this album now I've got it, give it an occasional outing.
