britishcomposer described Ladislav Kupkovic in this way:
"You always thought that music took the wrong course in following Richard Wagner?
Then take this lovely Mendelssohnian musician to your heart!"
I do think that's a nice piano quartet (although I think I'm hearing some jazz syncopations that mark it as clearly 20th century). Thank you for posting it!
I just wanted to make you aware of a contemporary composer who's very consciously writing music in a Haydn/Mozart vein, so unironically that I've actually described this music as a little frightening:

I dunno about frightening, but I found the samples pretty boring.
I'm heard some lovely modern music written in old styles (of various types) but this one....meh.
Mr. Busch does have a reputation for being prolific, anyway (look him up in the New York Public Library catalog (http://catalog.nypl.org)- also has his own homepage (https://amc.net/DennisBusch) with a list of works; some 570 opus numbers listed.) Not claiming anything else about him and not surprised that his music might be dull (Sturgeon's law and all that.)
I have uploaded Thomas Schmidt-Kowalski's Piano Quartet No. 4.
However, something went wrong: the file doesn't unzip.
Sorry for that! I am currently uploading a newly created zip-file.
EDIT: after two unsuccessful attempts the new link is on. Hopefully it works!
