(Almost) all the best bits from Mozart's opera, impeccably sung. Some might prefer Kurt Moll to Paata Burchuladze as Il Commendatore on stage (Moll is physically huge, which adds to the effect), but Burchuladze's bass is still earth-moving. Being picky, Don Ottavio's aria "Il Mio Tesoro" is missing and you get "Dalla sua pace" instead. Both arias are in the full recording of this production, although Mozart actually intended it to be one or the other; some tenors can't cope with "Il Mio Tesoro" as it's very demanding, so Mozart offered an alternative.
The famous Commendatore scene at the end is the best version of this that I've heard, although Ramey seems to be a bit low in the mix until the demon chorus joins in.
Also, if I'm being slightly picky, Donna Anna (the dignified one) and Donna Elvira (the nutty stalker) sound rather similar here. That's not really the fault of the sopranos involved.
