Metal is a lot like classical and a lot of metalheads enjoy it. The problem is that most of them go for classical music that imitates modern works and loses the beauty of the symphonic form; you know, the stuff that's trendy because it's easy for brainwashed moderns to think they appreciate classical through its modernized, boring form. Fuck Eric Satie and Charles Ives.
I disagree: Whether it's neo-romantic boring movie soundtrack bullshit, or twelve-tone dissonant trash, it is my experience that metalheads have enough balls to say no to the lies of both.
Most metal heads, if they care about classical at all, drift towards the more illuminated figures in its history.I am very happy that metal is one of very few alternative musics left that is willing to call people like Steve Reich and Eric Whitacre, as well as people like Stockhausen and Elliot Carter, out on their bullshit. No metalhead, not even me, would ever pretend that our current generation of composers has surpassed the relevancy, let alone the general achievements, of every single previous era of European music.
I guess I don't see the trend you do? Most classical of choice for metalheads, especially on this board, seems not to be "modern" or "boring" at all.
