A big disappointment, visually speaking, occurs in No. 4's finale, where the supposedly battling timpani players look more like they're having a polite discussion (a far cry from Seiji Ozawa's Boston Symphony video where the players take fierce and menacing stances). Likewise, the snare drummer's relaxed, Zen-like posture in Symphony No. 5's first-movement climax in no way suggests a Herculean struggle against the orchestra.

But ultimately it's the music that counts, and considering that Nielsen is still not a major presence in the concert hall, for most people in most places this handsomely produced DVD set likely will be their only opportunity to actually see all six symphonies performed. As a bonus, Dacapo includes Karl Aage Rasmussen's intriguing Nielsen documentary that reveals many interesting details about the composer's personal and professional life. The video quality is excellent, while the audio reproduces a heavy hall reverberation that was better clarified on the CD versions with these same forces. No matter, it's perfectly listenable, and overall this DVD set will prove immensely valuable to Nielsen fans.
