I've owned several Thuille discs, including the piano quintets & the symphony/piano concerto; however, I cannot believe a 1* rating for this recording, esp. from a presumed professional musician who likely did not even listen to the disc (my guess just from perusing that review). Thus, I must rate this recording highly just to provide a more representative overall evaluation.
When I listen to classical musical recordings to provide an opinion (and I'm not a musical professional), I like to judge the music on the composer's skills (of course, some are better than others), the quality of the performance, and the sound reproduction. Thuille was (at least initially) a friend of Richard Strauss, who admired his composing skills; he writes in a late Romantic style, more Brahmsian that in the mode of the eastern Europeans; this music is dynamic and contains some lovely melodies, esp. in the slow movements. Triendl (on piano) & the Vogier Quartett perform with conviction and modulate this music wonderfully. Finally, CPO is one of my favorite labels and their skills at recording music are beyond question. All put together, I would give this performance and disc at least a 4* rating (upped to 5* as mentioned above) - the quality of the music writing may be a notch below the 'greats' of the late 19th century, but some might even dispute that statement. This is a disc at least worth sampling, then read a little about the composer, and finally make a decision.
