Barry--
When you say of M6, "I think that it was prophetic of the coming European disasters - disasters on a global scale," you are apparently in agreement with Tony Duggan, who says in his analysis of M6,
"It has always seemed to me appropriate that the work’s 1906 premiere took place in Essen, the cradle of German heavy industry. All those driving, relentless, militaristic rhythms, mechanistic percussion and harsh-edged contrasts that permeate so much of this work have always seemed, to me, to share kinship with the place where the work was first heard. Here were the foundries and factories that put the iron in The Iron Chancellor and built the guns that would spill the blood in his "blood and iron" when fired in World War One, the cultural pre-echo of whose cataclysm eight years later the work seems partly to illustrate. A case of Mahler the sensitive showing himself in tune with his times, I think. So I believe this symphony is, first and foremost, a twentieth century work. Perhaps the first twentieth century symphony. It breathes as much the same air as Krupp as it does Freud, and its concerns are those of our time because so much of our time was formed in the furnaces of Essen as in the consulting rooms of Vienna."
Listened to with that in mind, M6 becomes a somewhat different symphony--and perhaps clearer.
Very interesting.
