Outdated, schmoutdated! It's quite astounding, really, to think that composers of the mid-to-late 20th century declared that the milenniae of music before them was outmoded and primeval. Like with most postmodern movements, their school of thought conflicted with what we consider to be 'natural'—in this case, the tonal intervals perceived by the human ear. Twelve-tone music, serialism, atonality, whatever you want to call it—it's an interesting (and sometimes useful) construct, but it greatly diminishes the beauty of music, in my opinon. Rather than flow with my soul, it goes against its grain. I'm not saying it's bad music, I'm just saying it's not beautiful. To me.
But, like you said, each to their own. I'm glad to see there are still composers out there who create music "the old-fashioned way."
