I agree with the assessment of Nielsen. Although he is clearly talented, it just doesn't offer enough that's emotionally rewarding enough to make me to invest too much time or money. I have the symphonies, and the first three are ok, the fourth interesting, the 5th irritating (I HATE HATE HATE that snare drum) and loath the 6th. I "get it" -- I know what he was trying to do with the sixth, but it just doesn't do anything. So I don't care for Nielsen, with one huge exception: the opera Maskarade is a wonderful, funny, delightful work that was so unexpected. Before totally giving up on Nielsen, you ought to try it!
