This performance promised to be a welcome reunion of the New Zealand Symphony Orchestra and Edo de Waart with Mahler, after their thrilling Symphony No. 3 earlier in the season. Unfortunately, this promise was not quite fulfilled in the composer's next work, with de Waart's interpretation of the Fourth Symphony sounding rather limp and shapeless in comparison. The concert was actually titled “Four Last Songs” despite the relative brevity of this cycle when compared to the Mahler that followed, but it was these songs that impressed far more with the radiant Christiane Libor on hand.
The songs were performed in their published order, starting with Frühling. Libor has an idiomatic grasp of the Straussian idiom, this first song sounding all the world like one long continuous phrase, even the difficult low passages ideally projected. Hers is a large voice (she counts Isolde and Senta in Der fliegende Hollander amongst her stage roles) but was never unwieldy in tackling Strauss's melismatic melodic lines. This vocal amplitude paid dividends as she soared to a magnificent pinnacle at the end of Beim Schlafengehen, filling the hall with immense glowing tone on the word “tausendfach”. As well as producing a consistently glorious tone, Libor showed a keen understanding of and engagement with the text. This made Im Abendrot the emotional highpoint of the cycle, Libor's unusually clear diction rendering the final phrase “ist dies etwa der Tod?” almost unbearingly poignant.
On the podium, Edo de Waart unfolded the songs at a leisurely pace, allowing the audience to luxuriate both in Libor's voice and the lustrous depth of the orchestral playing. They made a most sensitive accompanist to their soprano in quieter moments, coaxing the orchestra to a lovely autumnal hush in September but never skimped on volume when required, unleashing a great orchestral torrent of sound in the final song. Concertmaster Vesa-Matti Leppänen was superbly poised and lyrical in the serene violin solo in Beim Schlafengehen and the horns were on superbly glowing form in their prominent parts throughout.
It was an interesting idea to have this Isolde-sized voice take on the solo part in Mahler's evergreen Symphony No. 4, usually the province of lighter voices. I'm not sure it quite worked, even though Libor once again pointed the words with great attention. Nevertheless, this impeccably sung and well thought-out performance lacked something of the sense of childlike wonder that a more lyric soprano voice can bring to this magical movement. De Waart was at his most alert in this movement, uniting the disparate sections and little orchestral touches pointed deliciously.
