Coloratura may not be Netrebko's strongest point but it is strange that, with a 2005 Rigoletto, her Caro Nome aria is passed over for the Act III trio with Maddalena and Sparafucile. This deals out solid Verdian drama - her character, Gilda, is about to be murdered - but Netrebko's presence is minimal.
All is forgiven, even her avoidance of the final top E flat, in the Mad Scene from Donizetti's Lucia di Lammermoor. The lustre and sheen of the voice captivate; scurrying footsteps and stage business, intrusive elsewhere, almost heighten the drama.
Nicest touch is the ghostly glass harmonica which blends eerily with her voice when the incense burns and the holy tapers glow.
Fringe divo benefits include a single line from Dmitri Hvorostovsky's Andrei in War and Peace and a passionate partner in Joseph Calleja for the love duet from Act I of Offenbach's Les Contes d'Hoffmann.
This is a fascinating document, perfectly timed for the launch of a new season of live screenings from the Met.
Next week, playing in theatres around the country (including Auckland's Rialto and Bridgeway), Netrebko plays the tragic queen in David McVicar's production of Donizetti's Anna Bolena.
