Query: Klemperer on Qualuudes

Klemperer's Zauberflote is likely the most wonderful opera on record. I thus looked forward to this with great expectation, especially with Geraint Evans - a formidable voice - and Elisabeth Soderstrom - Swedish beauty. Unfortunately, from the first downbeat to the end of Act 2 nearly 100 minutes later there is absolutely nothing but plodding, lifeless noise. Reri Grist's voice is especially cloying. Let's just say Klemperer's stick is flaccid and the ensemble never gains momentum. To represent Mozart's nobility with any meaning requires pace, spontanaeity, and surprise - all absent here and obviously the reason this set is out of print and frankly out of breath.
