Searching for an early Bruckner recording

Searching for an early Bruckner recording
Emil Kahn (1896-1985)
Recently, a contact in Germany sent me the following e-mail:

Looking at your Bruckner website, I noticed that you are missing one early recording, made by Electromusik, Stuttgart, in 1934:

Großes Orchester
matrix 0587 4. (romantische) Symphonie (A. Bruckner)
2. Satz I order number 5037

matrix 0588 4. (romantische) Symphonie (A. Bruckner)
2. Satz II order number 5037

matrix 0589 4. (romantische) Symphonie (A. Bruckner)
2. Satz III order number 5038

matrix 0590 4. (romantische) Symphonie (A. Bruckner)
2. Satz IV order number 5038

Although neither director nor orchestra are specified, the musicians surely consist of members of the Stuttgarter Philharmoniker, most probably lead by Emil Kahn who worked anonymously for the company. If movements 1, 3 and 4 were also recorded I don't know...

As an FYI, conductor, Emil Kahn (1896-1985) recorded many symphonic works for the Music Minus One label. He left his native Germany in 1933, came to the United States in 1935 and taught at Montclair (N.J.) State College until 1970. Later, he led the Senior Orchestra of New York for 13 years. His last appearance as conductor was at Carnegie Hall in May 1983. Orchestras for which he was guest conductor included the Vienna Philharmonic, the London Symphony and the N.B.C. Orchestra. He was, in 1945 and 1946, musical director for the Ballet Russe. In addition to his Music Minus One activities, he made at least one commercial recording with the Stuttgart Festival Orchestra.

A contact at the Deutsches Rundfunk Archive has provided the following observation:

„Electromusik“ is a small, nowadays completely unknown label. Electromusik GmbH was founded around 1930 in Vaihingen and, in addition to inexpensive „department-store-records“ for the "Elton" label, also produced many small editions and private pressings for Swabian artists. The fact that „Electromusik“ brought a Bruckner symphony onto the market is rather atypical. Emil Kahn worked for the company indeed. He was commissioned to put together a band for recording dance music [!], which he formed from members of the Stuttgart Philharmonic. This then played as „Elton Dance Orchestra“. Emil Kahn was Chief Conductor of the Stuttgart Philharmonic of Süddeutsche Rundfunk AG until June 1933. He was fired because he was Jewish. He emigrated in 1933. In 1936 the production of „Electromusik“ and „Elton“ records was finally stopped.

The original contact says that he owns the recording, but does not have the ability to dig it out of a storeroom. If anyone has any further information about this recording, please contact me.
