2024 stock. The album Entschlummern sollst du, sollst entschlummern (engl.: Thou shall slumber, slumber, shall thou) brings us the first ever released recordings of four string quartets by Frieda Bertelsohn Martholdy (1878 -1907), a composer yet unknown to most of us. The first listening makes undoubtedly clear what an original voice as a composer and what an astonishing achievement from the performers we are witnessing here. Frieda Bertelsohn Martholdys thoroughly modern sounding music fluently integrates a pronounced romantic quality, completely innocent of any of the aesthetic conflicts that 20th century music later challenged providing a candidly bewildering and enriching listening experience.
