When I saw the price of this disc I was suspicious that it might not be the complete opera; rest assured it is the whole work, with the bonus of tasters of other HD issues.
La Scala's production can be described as traditional and sumptuous - sets, costumes, lighting, makeup, direction etc. all first class. The two main principals, Angela Gheorghiu and Ramon Vargas need no introduction, while Roberto Frontali as Giorgio Germont has a fine voice, younger-sounding than is sometimes found in this part. Lorin Maazel holds everything together expertly and draws some fine playing from the La Scala orchestra.
Gheorghiu and Vargas are in fine voice, and sing their solos most affectingly. She acts her heart out, from flashing eyes to quivering bosom, while he moves well but does not always carry the part in his facial expression; he does show a little more emotion after a well-deserved slap from his stage father in the finale to act 2.
The minor solo parts, and the renowned La Scala chorus, are all excellent. The La Scala audience is generous in its appreciation and gets curtain calls after each act.
Picture quality is as good as I have seen, with just a little movement judder very occasionally from my Oppo player. Shots are well-chosen, vision control very good. I have seen criticism elsewhere of the audio balance between soloists and the rest, but I would disagree. I wish I could say that the sound of La Scala is faithfully reproduced, but since I haven't had the pleasure of being in the audience in Milan I can only say that the sound is natural and believable. Those used to having soloists individually miked may notice the difference here; the impression I have is of surround microphones located somewhere near the front edge of the stage, so that when soloists turn away from the audience the quality of their voices changes in a natural manner. Whereas they blend with the orchestra and chorus, they are neither over-prominent or submerged - Gheorghiu, of course, is well able to project her top notes so as to be always heard.
In general the audience is pretty quiet - there is nothing worse than coughing from the audience as well as Violetta in her death scene - and the most noticeable extraeneous noise is what I take to be air-conditioning just audible in quiet moments between the notes. My comments refer to the DTS-master 7.1 tracks which make good (but not obvious) use of the rear channels (except for the tambourines flourished by the female dancers in the finale to act 2, which wander about sonically).
Comparisons between this recording and the similarly traditional LA opera production on Decca blu-ray are interesting but too lengthy for this review. Suffice it to say that both are excellent; Decca's sound is a little more polished but Arthaus has the appearance of honesty; I'm glad to be able to say that I can enjoy both versions.
