I was a big fan of the late Welsh soprano Margaret Price. This recording of Mahler lieder is not up to her usual standards, however. Part of the problem, to my ears, is the accompanist, Thomas Dewey, a good many of whose contributions are distracting -- particularly in the Wayfarer and Knaben Wunderhorn selections. Price might have been shown to better advantage with the orchestral accompaniments. The Ruckert lieder fare better in his hands, though I could do with a little more restraint on the pianist's part in "Um Mitternacht."
Back to Price, she too does better in the Ruckert lieder than in the other selections on this disc. Also lovely is her rendition of "Urlicht" from Des Knaben Wunderhorn. Overall, however, this record is a disappointment. Those seeking top notch Margaret Price should look for her recital of Schubert lieder accompanied by Graham Johnson, her Wigmore Hall recital of Schubert, Mahler, and Strauss lieder (accompanied by Geoffrey Parsons), and her astonishingly good -- indeed, ravishing -- performances with Abbado of Berg's Lulu Suite and the Altenberg Lieder.
For more satisfying Mahler with female singers, try Janet Baker (with Barbirolli, not the fairest comparison because of the wonderful orchestral accompaniment), Christa Ludwig (who has recorded both with piano and orchestral accompaniment), Anne Sophie von Otter, Jessye Norman, and, for something special, Kathleen Ferrier's recordings of Mahler lieder (if you can find them).
