There are few 'perfect' recordings of anything, let alone this opera.
However, this version, re-issued on CD at mid-price, combines excellent, atmospheric sound; energetic, but not hard-driven conducting; and, most importantly, the beautiful voice of Anna Moffo.
While the soprano is the star of any Traviata recording, the other principals are also important. Richard Tucker and Robert Merrill are pretty good, but I have to admit I prefer Nicolai Gedda and Rolando Panerai on the EMI Sills/Ceccato recording. That, too, is also very enjoyable but the conducting is a bit slow in parts.
Even more that the great Maria Callas, Anna Moffo plays the three 'sub-roles' very well indeed and she effortlessly handles the different demands of the role .
If you like La Traviata, you'll have several versions - I have six - but this will be at or near the top. Highly recommended.
