The Austrian composer Frida Kern (Vienna 1891 - Linz 1988) was a student of Franz Schmidt and Eusebius Mandyczewski among others and left a body of 280 numbered works in all genres. The Belgian-Israeli harpist Rachel Talitman has released a CD of chamber works by Kern on her independent label Harp & Co. (https://www.harpandco.be/?p=343). Getting hold of a physical disc is not so easy, it seems, but the recording can be found here (https://youtu.be/yCzWVME9DPM) for the time being.
