I've heard Brüll's piano concertos and some solo works. Very Brahmsian sound, but I can't say that I am exactly running back to this composer to hear more. It isn't bad, though.
Also, word of advice: if you want to type a German composer's name that has an umlaut but don't know how, simply put an 'e' after the letter that needs it. For example: Brüll -> Bruell.
