Call me old-fashioned, but I'm very skeptical about all this "experimental" music, if you can even call it music. Let's be honest, it's awful!
I'd prefer something by Bach or Chopin with a melody. Now THAT'S real music.
When it comes to this junk, I used to follow the same train of thought as you, but the fact is that you just have to look at this music from a different angle. It's still music, but it chooses to go in a direction that's completely different from music as we know it traditionally. The music becomes a lot more scientific than it does artistic, with the underlying principle being that music doesn't have to follow any rules, period.
I worked for five years as a recording engineer at UC San Diego, where their music program focused primarily on what they called "new music." Over my years there with the music department, I learned to understand a lot of what new music was all about.
Even so, I never really learned to like it. Very rarely did I encounter a piece that I thought was really cool and deserved credit for being more than just some bizarre science experiment in sound. But I guess this kind of music isn't necessarily about the listener, and testament to that fact is the number of recording sessions I just cringed my way through...
I'm not even sure a lot of the performers really liked this music all too much, either, to tell you the truth. While there were definitely some fruitcakes that were way into it, I think a lot of the performers participated in the new music thing only because they were expected to do so as members of the staff/faculty, perhaps just to please their superiors. What's really amazing is that most of them came from some serious musical backgrounds, nearly all of them classically trained to the concert performing level. I recorded a lot of piano concerts where they'd play this kinda shit for a half hour, then turn around and play a whole set of Rachmaninoff preludes flawlessly. Kinda weird to see the two musical worlds juxtaposed like that, but hey, it's a university, I guess they've got to do some sort of "research" somehow.
I guess you just gotta be into it to enjoy it. I never was able to do that, myself, but I don't think that necessarily makes it "bad" music. It's just different. Probably way too different for most peoples' tastes.
