for (Regina, Rosa, Ruth & Rachel) is a musical and scenic collage by Ariel Efraim Ashbel and Rachel Libeskind, with composer Maya Dunietz, singer Jessica Gadani, and cellist Lori Goldston. A large-scale live graphic work was created in the Festsaal of Sophiensæle during the performances.

Four names shape the narrative: Regina, Rosa, Ruth and Rachel. Research into Jewish women in Berlin-Mitte soon transcended geographical and temporal boundaries, broadening the scope of reference points. Regina refers to Regina Jonas (1902–1944), the world's first female rabbi, born in the Scheunenviertel. Rosa refers to Rosa Luxemburg, who spoke at Sophiensæle in the 1910s and 1920s, as well as to the Munich entrepreneur Rosa Klauber (1820–1901). Ruth recalls Ruth Klinger, an actress and co-founder of the experimental cabaret Kaftan in the 1930s. Rachel connects several figures: Rahel Varnhagen (1771–1833), an icon of Berlin salon culture; the Yiddish poet Rokhl Korn (1898–1982); Rahel Hirsch (1870–1953), the first female professor of medicine in Prussia; and multimedia artist Rachel Libeskind herself.

The biographies of these women raise questions about feminist agency, solidarity in times of crisis and artistic resilience. The work sees itself as a glimpse into the past, present and future of Yiddish culture in Berlin.

Between 1870 and the early 1920s, nearly three million Jews left the Russian settlement zone. Many came to Germany and to Berlin's Scheunenviertel, which is where Sophiensæle is located today and where a vibrant Jewish center emerged. Drawing on sources from early 20th-century Yiddish theater culture in Berlin, the ensemble presents new compositions by Maya Dunietz as well as reinterpretations of unearthed texts and songs. Five performers translate this diversity into a tapestry of voice, text and sound: experimental sound meets opera singing, accompanied by harp, piano, cello and accordion. Archival material and accompanying projections are translated into a spatial, sensory experience, bringing a largely erased urban culture back to life.
