Closing the evening, Brewer took on the great Liebestod from Tristan and Isolde, waiting on stage while the orchestra gave a stirring account of the Prelude to Wagner's opera.
In concert, with playing of this stature, one was even more aware of the finesse of the scoring and, thanks to the piece's extensive use on the soundtrack of Lars von Trier's recent film, Melancholia, it provided an effectively ominous introduction to Isolde's leavetaking.
For a woman who puts great store on building a rounded character throughout a staging of the whole opera, Brewer gave us a magisterial farewell, only slightly marred by the occasional blowsy top notes.
Completing the first half of the concert, Otaka had us on tenterhooks with the fluttering anticipation in the opening pages of Strauss's Death and Transfiguration.
The work's inevitable narrative soon took hold, with shapely woodwind playing and, at the other end of the decibel spectrum, a thrilling workout of the great Ideal theme.
Immediately after interval, before the tragedy of Tristan, Wagner's more modest Siegfried Idyll, despite smaller forces, brought forth just as volatile, if happier, emotions than the earlier opera.
