Query: NATIONAL, NOT INTERNATIONAL

IN OPERA, SOME WORKS ARE VALUABLE BECAUSE OF THEIR PLACE AND SIGNIFICANCE IN A NATIONAL MUSICAL CANON, BUT THEY DO NOT TRAVEL WELL. I MEAN, THEY FAIL TO CAPTURE LISTENERS THE WAY THE GREAT OPERAS OF EVERY COUNTRY DO. THIS IS THE CASE WITH THE LANTERN. THE SINGERS ARE ALL EXCELLENT AND SO IS THE CONDUCTING . . . BUT I FOUND THE MUSIC BORING AND AT TIMES ALMOST UNLISTENABLE. I HAVE JUST DISCOVERED THE LIKES OF FIBICH AND NOVAK, LOVE THEIR SYMPHONIC AND CHAMBER MUSIC, BUT CAN UNDERSTAND WHY THEY HAVE REMAINED IN THE BACKGROUND WHEN COMPARED TO THE TWO CZECH MUSICAL GIANTS, DVORAK AND JANACEK.
