It's like literally everywhere! I almost exclusively listen to contemporary Western classical music (WCM) and it's never been more exciting and better. There has never been a time where there are so many different dominant styles at the same time. There are atonalists [1] like Unsuk Chin, Jennifer Koh, Charles Wuorinen, Fred Lerdahl. There are neo-Romanticists like Jennifer Higdon, Michael Torke, Thomas Ades. There are minimalists like Caroline Shaw, Max Richter, Bent Sorensen, Christine Southworth and their ur-father Philip Glass who still writes music at 86.
If you're interested in my full opinions about the cultural force of contemporary WCM please read this [2] HN comment of mine.
Seriously contemporary WCM is awesome. It's very cliche but "if you don't like it, move on".
> In my opinion, this is a racist response by mainly European composers to the popularity of Jazz music which is associated mainly with African Americans, from whom the source originated. They were jealous of what they perceived as the novel rhythms and harmonies, but instead of building off that or inventing something new that still had rhythmic and harmonic value.. they did this
Meh, I don't think this is true at all. They're just entirely different artistic traditions. Just because haiku exists doesn't mean American novels can't.
I don't dispute that tons of normie classical music listeners (like r/classicalmusic) are racists/elitists. These people almost exclusively listen to old German common practice stuff like Bach or Mozart. They pretend that 18th century German music is somehow superior to everything else. Almost none of them would consider Ligeti or Glass even classical music. This is not the contemporary Western classical music scene at all. It seems like you may not have a sophisticated enough understanding of this subculture, imho.
