Simone Young is superb, the orchestra is superb, Der Wanderer, Mime, and Fafner are all excellent. The recording has raw power and is very well-balanced. More than any other conductor on record, Young understand how to make the most of Wagner's brilliant switching between his use of tubas and horns - wonderful stuff. Young 's conducting is a force of nature. But, oh dear, Siegfried and Brunnhilde just don't deliver. Franz had been good enough, just, in the opera house for a number of years - acceptable in Berlin but perhaps a bit past his sell-by date in Bayreuth for the late Giuseppe Sinopoli. But here, he is struggling - indeed, may have been unwell - and the pumped vibrato is at times embarrasing as he negotiates some of the longer lines: clearly he is trying to act as well, and some of his vocal acting is good and touching but one finishes up dreading the approaching 'big moments'. Foster, well, she doesn't appear to know the role thoroughly enough. She is out of her depth and what quality the voice may have vanishes as soon as it comes under pressure: the random and over emphatic vibrato all but destroys any residual sense of tuning and beauty her voice may have, probably does have, in a smaller musical environment. This is such a shame because Simone really is something and deserves better. Reviews of Foster on stage have been favourable, so it may simply be that her voice has not been well captured by the microphones - as was the case for Thielemann's Linda Watson at Bayreuth.
