Maybe 3.5 stars, for the basic quality of the voice is lovely -- it has a nice quick vibrato and a pleasant warmth in the middle to upper-middle of its range -- but as other reviewers have commented, there is a sameness to the items in this recital that make it less compelling than debut recitals by singers like Rysanek and Price. I have seen Netrebko twice in live transmissions from the Met, and she's a fine natural actress (i saw her as Elvira in "Puritani" and as Gounod's Juliet) and the voice was in good condition, but here, about four years earlier in her career, her coloratura singing is a bit approximate even though she seems to be singing carefully (at the end of "Non mi dir" and in the florid sections of Lucia's first aria and cabaletta). The top of her voice can get a bit shrill, but that could be an artifact of the recording. Netrebko was 32 when this recording was made -- the reviews of her performances since have been positive, and she made a nice recording of Russian arias, so she grew as a singer. If you want to hear her in better voice, I recommend the Russian album -- texts and translations are provided, so you don't need to worry about the unfamiliar material and language.
