beautifully sung and recorded - highly recommended

'played on period instruments', according to the blurb. Hmmm. Think I'd go for Kitajenko on Chandos:

Having listened to the excerpts at the link posted by Gareth, there doesn't seem to be anything unpleasant about the orchestral sound. Not all period ensembles sound the same any more than "modern" ones do. What I heard sounds quite fresh and delicate, some lovely woodwind, and as far as I can tell from the samples the recording quality is excellent. And the singing sounds far better than that on the Chandos recording, espeically Ivonne Fuchs. I find Anne Gjevang's effortful and constipated contralto voice positively unpleasant in the older version.
Yes, it sounds nice and fresh. But, making a comparison with the Chandos recording, the strings are very thin and reticent. Not for me, this new release, but I can see why it might prove attractive...
Yes, Fuch's singing is what really captured my attention.
