Opernale, the Institute for Music and Theatre in Western Pomerania, is presenting a world premiere production with compositions by the composer, pianist and singer Luise Greger, who was born in Greifswald in 1861 and died, a victim of the Nazi euthanasia programme, in 1944. Luise Greger – eine pommersche Gans (=a Pomeranian goose) (https://opernale.de/events/opernale-2021-luise-greger/) will receive its premiere performance in Greifswald on 20 August. As yet there's no information about a broadcast or a recording.
The orchestral score of Greger's Märchenoper "Gänseliesel" was rediscovered in Kassel, where Greger lived, in 2017. It has been digitised and is accessible on the Kassel University library website (https://orka.bibliothek.uni-kassel.de/viewer/image/1511175017375/1/).
In 2019 a Luise Greger festival was held in Kassel. More information can be found on the composer website (http://www.greger-luise.de).
A charity concert to celebrate the composer's 160th birthday was broadcast online and is available on Youtube (https://youtu.be/lkE9GVJM73Q).
Greger was mainly a composer of Lieder. See this article in English (https://hampsongfoundation.org/resource/restoring-luise-greger-a-renaissance-in-progress-2017/) by Paul-André Bempéchat.
