A Golden Age of Jewish music almost forgotten - the songs captured in 1930s‘ Berlin by Hirsch Lewin on his Semer label. The Semer Ensemble brings this astonishing music back to life with critically acclaimed concerts and their first album, recorded live at the Maxim Gorki Theater, Berlin, in November 2015. 1920s Berlin, a Golden Age of Jewish music and musicians. In this milieu we find Hirsch Lewin, formerly a forced laborer conscripted to Germany from his native Vilnius during World War I. After the war, Lewin decides to remain in Berlin, finds work in a bookstore, and eventually starts his own business: the Hebräische Buchhandlung (Hebrew Bookstore), Grenadierstrasse 28. The year is 1930. In the midst of Berlin‘s immigrant center, the Scheunenviertel, Lewin sells books in Hebrew; history books, children‘s books and more; prayer shawls, candles and other religious items. His speciality: gramophone records! In 1932, Lewin creates his own label, „Semer“. One year later, the Nazis come to power, forbidding Jewish musicians to perform in non-Jewish settings. Semer becomes a Noah‘s Ark for Jewish musicians who have nowhere else to go. For five years, Lewin makes recordings at a feverish pace, creating a precious time capsule of a world facing annihilation. On November 9, 1938, SA hordes attack the Hebräische Buchhandlung, demolishing stock and store, including 4,500 recordings and 250 metal plates. The memory of the Semer label falls into oblivion for the next 60 years.
