The thing that interests me in your comment is why would you try for thirty years to "get into" something? Or do you mean you don't much care for his music, but no rush in jumping to conclusions...

Do you care for Berg or Webern, by any chance? (Or Stravinsky's serial music for that matter)

I'm not surprised. If I understand his 12-tone system correctly, you need to use each tone equally frequently throughout the piece. But that is the musical equivalent of white noise, or the the equivalent of saying that a novel needs to use all words equally frequently. In order to convey information the content needs to be distinctly more frequent.

Try Violin Concerto, Op. 36 by Hilary Hahn & the Swedish Radio Symphony Orchestra
