It is that obsessive question about what would one take if he were to spend the rest of the life on a deserted island. I would definitely take one of the Pergolesi's Stabat Mater interpretations.
I have just received this CD at the office (I dislike Amazon sending through UPS at home), and couldn't wait the end of the day before unsealing the CD and listening it on my PC's CD unit on a pair of Sony headphones. Audiophile setting this is not. But, even so, it was good enough to realize what a superb interpretation this is.
As the previous reviewers already said, the voices of Lezhneva and Jaroussky match very well, and blend nicely in general.
"Laudate Pueri" comes as a very nice surprise, especially listening to the countertenor capabilities of Jaroussky.
For my baroque taste, Lezhneva's voice is a little bit too profound in the lower registry. Something better fitted with Rossini. But, in the upper registry, she represents all the value of the baroque music, demonstrating a very high pitch and superb tremolos. For the upper registry I would recommend track 4 from http://www.amazon.com/Alleluia-Julia-Lezhneva/dp/B00ABNLASC/ref=sr_1_1?ie=UTF8&qid=1392753757&sr=8-1&keywords=lezhneva, while her http://www.amazon.com/Rossini-Opera-Arias-Gioachino/dp/B003V8SW6C/ref=sr_1_4?ie=UTF8&qid=1392753847&sr=8-4&keywords=lezhneva is a very good example of how nice her voice is developed for this composer.
Diego Fasolis and his Barocchisti are well known specialists in the baroque music, so their very good interpretation shouldn't come as a surprise.
Summing, this is a very good interpretation of a baroque jewel, by some accomplished musicians of the present moment. But, would I take it on a deserted island? I don't know. My preferred interpretation remains http://www.amazon.com/gp/product/B000006321/ref=cm_cd_asin_lnk , but this new one comes to a very close second place.
I would even say that both interpretations together give me a better understanding of how beautiful Pegolesi's music is.
In the end, I can only admit my inability to separate very well the value of these interpretations. That is why, I would be very grateful to everyone who listened both, to leave me a comment with their opinions.
EDIT: I was so excited writing about Stabat Mater, that I simply forgot the surprise - at least, for me - that "Confitebor tibi Domine" is. The interpretation is magnificent, and the surprise comes with how strong and full the music is with such small resources (in term of number of instruments and voices). It is another demonstration that good music doesn't need a lot of noise to show its value. And, "Sanctum et terribile nomen ejus" (track 24) shows again - if needed - the great talent of Jaroussky, becoming my favorite track on this CD. Bravo!
