Carl Neilsen is one of those composers whose skill and talent I can hear but, for some reason I don't know, not a single piece of his I have ever heard has ever moved me. I know that isn't the reaction of most other people, he's a composer who goes in and out of popularity, there was a major revival in interest in his music in the United States in the 1970s. I hope you're someone who he does speak to but I doubt he ever will to me after fifty years of listening.
Update: Anyone who believes Lenny Bernstein could conduct a "definitive" performance of any piece of music he didn't compose, himself, is too stupid to have an important opinion about music. And that isn't even getting to the FACT that Bernstein was one of the most notorious distorters of musical scores who ever had a major career. Gunther Schuller documented that in his classic study of recorded performances and their deviation from or adherence to the stated intentions of the composer, The Compleat Conductor.
Apart from pre-recorded electronic composition without any live performance elements, the common declaration that this or that performance is "definitive" is the creation of idiot critics who don't know enough about music to have an important opinion about music. As just about every composer who has ever performed or conducted their own music performs a composition differently every time they perform it, especially those pieces which rely on soloists, singers, other performers, the entire concept of "definitive performances" is professional critic bull shit.
