Carl Nielsen's two wind concertos - the Flute Concerto and the Clarinet Concerto - keep students and professional musicians busy all over the world today. However modest and mainstream the scoring may look at first sight, the exploration of the potentials of the ensemble is most interesting. The Flute Concerto was first performed in Paris, a provisional ending immediately being replaced with the one now in force. The presence of a solitary bass trombone is notable, and suave manners tend to give way to brief displays of temper all over the place in this piquant work (much too capricious to qualify as "pastoral" in any comforting sense).
