Even toward the end of her career Christa Ludwig was in lustrous voice and sang with an innate understanding of these songs.

Christa Ludwig was one of the leading operatic and recital singers of the post war generation... The disc devoted to lieder makes for very rewarding listening. The groups by Strauss and Mahler strike me as being particularly fine. Even towards the end of her long career Ludwig was able to call upon the resources of tone which these songs so often demand. This is not to imply that the offerings of Schumann or Brahms are in any way inferior. In these, too, she is in lustrous voice and sings with an innate understanding of the idiom. The programme is artfully chosen not only to present composers with whose music Ludwig had a particular affinity but also, just as importantly, with regard to the inevitable limitations the years may have placed upon her vocal resources. Suffice to say there is little or nor hint that we are listening to a singer aged 65. ...[T]he whole lieder recital is taken from a disc entitled ‘Farewell to Salzburg’ and comprises the programme which she chose for her final recital in that city in August 1993. The recordings themselves were made in the previous January during performances in the Schloss Grafenegg in Haitzendorf, Austria... The discs will give much pleasure for they are full of high quality artistry and all admirers of this great singer will want to snap up these recordings.
