Julius Bürger [anglicised to Burger] (1897-1995) grew up in Vienna and studied composition with Franz Schreker. He is one of many composers forced into exile by the rise of Nazism. In the very last years of his long life, he saw the fulfilment of a long held wish: to experience his music being performed. Baritone Ryan Hugh Ross brought out an album recently: A Journey into Exile – The Lieder of Julius Burger. There is a half-hour documentary about the making of that album on the Rediscovered Beauty website (https://www.rediscoveredbeauty.org/burger-film) and also a biographical article (https://www.rediscoveredbeauty.org/julius-burger).
I'm sure this is of interest.
Extracts form the album can be heard here (https://www.prestomusic.com/classical/products/8704451--a-journey-in-exile-the-lieder-of-julius-burger). Apart from the Lieder des Alters set, all of them could have been written pre-WWI.
Not my cup of tea, but others may enjoy this rather 'dark' music more than I.
