Query: Only for Gruberova fans

The minimalist staging and silly clothes are a turn off for such a historical opera. With some operas it can work well, but not this one. The stage direction wasn't much better.....really distracting.Gruberova is sadly well past prime, but could be fine in less demanding roles with a lot less high notes. She tries for chest voice in the low notes but just gets hoarsness. But the audience applause shows what a great following she has. The lady is gutsy to take on this role and I do admire her for that.Franco Vassallo was quite good, but a bit lyric for such a nasty guy. Made me want to hear him in lighter roles.Back to my Australia version with Sutherland
