Nury Halmämmedow (aka Nury Halmammedov, 1938-1983): String quartet (1976)

Нуры Халмамедов: Струнный квартет (1976 г.) 1. Moderato non troppo 0:00 2. Andante - adagio 10:09 3. Presto 17:32 from Melodiya LP C10 23097 001 (1985) The LP cover specifies the interpreters as Felix Leger (Феликс Легер), Vitaly Nikishin (Виталий Никишин), Shaya Braverman (Шая Браверман), and Valery Amelin (Валерий Амелин), however reliable this may be. Only of the cellist I could find any other trace.
