NB The other two reviews are completely misleading, for they are of other recordings (one historic, the other "classic") altogether.
I am no expert on Puccini, and Manon is not among my favourites of his output, but this one strikes me as being very adequate indeed.
The Penguin Guide thinks so, too, awarding three stars (its highest rating). In its expert view, "Miriam Gauci gives one of the most sensitive performances of this role on any set. The young Bulgarian, Kaludi Kaludov, is a clean-cut, virile Des Grieux ... impressive in his big moments. ... Vincente Sardinero makes a powerful Lescaut, and Rahbari is a red-blooded interpreter. .. even if it cost more, it would still be very recommendable."
I totally agree. Only the lack of an English translation of the libretto (though there is the Italian text) prevents wholehearted endorsement. But at this price, that's a quibble.
