Many pieces have Metallica looks really very much of the 19th century symphonic .: Master of Puppets, Fade to Black or One example, also For Whom the Bell Tolls has the qualities of orchestral onomatopoeia.
In order for the orchestral work has almost nothing to do S & M but - what this orchestra fabricated more in line with Hollywood movie music of the 70s and 80s. I hear the music, I see running along a coastal highway in my mind, and Magnum shaft-sequences and a woman with fluttering scarf in a carriage. In short, although the orchestra makes Bombast- and panoramic sound, but first would probably better suit radio than to metal, and secondly, he who hears something normally anyway?
Anyone who is interested with classical to fusion of Metallica, should listen to the early Apocalyptica Slices, who is interested in symbiosis of metal and classical music, the grab for Manowar (Gods of War), Nightwish and with a bit more gothic in it: Lacrimosa , at least as regards the unity of metal / rock and classical music. Because S & M there are none.
Otherwise, I recommend Wagner: Der Ring des Nibelungen, infected the character as almost as much hard ŽnŽHeavy in it, such as classical in Metallica.
Incidentally: Who would ever think of songs by Mozart, Schubert or Zelter stuffing with orchestral shenanigans?
Yes, but because gabŽs times in the '90s as a Hans Zender, who has dealt with Schubert's Winterreise similarly orchestral, won as the Kamen Metallica pieces here and has for the Frankfurt Music Prize.
And from perfect expression was top-heavy over-stimulation.
