From the Lotte Lehmann Archives of the Special Collections at the UCSB Library, the specialists sent me the following Lehmann recordings. They were all listed as “test pressings,” but only some of them were. The following list (in alphabetical order) offers the recordings they sent along with my remarks.

Andenken (Ich denke dein) (Beethoven) This is a test pressing for the recording Lehmann and Ulanowsky made in 1941 for Columbia.

Andenken

Auf Flügeln des Gesanges (Mendelssohn) This is a test pressing for the recording Lehmann and Ulanowsky made in 1941 for Columbia.

Auf Flügeln des Gesanges
Auf Flügeln des Gesanges, but from a live broadcast on 7 March 1948 with Ulanowsky. This was filtered by Ward Marston. The sound is so much more vibrant and alive than the test pressing that I can only imagine that the latter was pressed from a shellac or played from an acetate. Though Lehmann is seven years older, her voice sounds fresh and young. Sadly, the tape ran out before the end, so it’s incomplete.

Aufträge (Schumann) This is NOT a test pressing, but a live performance that hasn’t been identified. It isn’t the live 1941 Town Hall recording heard on Music & Arts with Paul Ulanowsky, nor is it from the 1950 appearance in Town Hall with Bruno Walter playing piano; he was also her pianist on 17 Apr 1950 in San Francisco, which was broadcast on the Standard Hour.
It could be the 15 Feb 1943 CBS radio broadcast; that included Schubert’s An die Musik and Schumann’s Aufträge; Howard Barlow, conducted an orchestra, but Aufträge was performed with piano.

Das Veilchen (Mozart) This is NOT a test pressing for the 1941 Columbia dates. It isn’t from the 10 or 30 July 1949 Recital at Emerson Junior High School, Los Angeles with pianist Bruno Walter which you can hear below.

Mild und Leise (Tristan und Isolde: Liebestod) (Wagner) This is NOT a test pressing, but rather from a live performance with the San Francisco Orchestra conducted by Pierre Monteux on 12 Dec 1943 for a radio broadcast for the (Chevron) Standard Hour, NBC. Though this isn’t the best performance Lehmann sang of the Liebestod, there are some fine moments.

Sehnsucht nach dem Frühlinge (Mozart) This is a test pressing for the recording Lehmann and Ulanowsky made in 1941 for Columbia, but you’ll hear the “improved” version below. Who knows what has been done to make it sound different.

Ständchen (Schubert) This is NOT a test pressing for the 1941 Columbia recording. Lehmann sang this so often, it’s difficult to know the origin of this recording.
