This one goes back to the original concept of the play, followed by the opera; a lot of different music and additional music. I have no way to comparethis with what was presented at the world premiere of this version in 1912, and the booklet indicates this is an updated version for the Salzburg Festival. In any event, the play is much too long and the opera lacks the punch we get from the revised all musical approach to the prolog and opera. This is interesting for what it is but probably would never be popular today. Kaufmann is outstanding as expected but even his role seems to be less interesting in this version. Magee is good and so is Mosuc but a lot of the additional music for Zerbinetta is really boring after a while, at least in my humble opinion., Recommended only if one really wants something at least approximating the "complete" history of this work.
