I have just come across this release. which may have been available for some time, on the rather obscure Swiss label Acanthus (ACM002) - there is also another CD (ACM001) with Huber vocal quartets, but, rather surprisingly, duplicates the "Vom Luzernsee" Ländler for piano duet, from ACM002! I'm sure, however, that the Walzer for piano duet, violin and cello will be interesting enough, and I anticipate echoes of Brahms!http://www.acanthus-music.ch/product_info.php?cPath=55&products_id=109&osCsid=86179ca2dfea79f05cbcbc10fc141c81 (http://www.acanthus-music.ch/product_info.php?cPath=55&products_id=109&osCsid=86179ca2dfea79f05cbcbc10fc141c81)
