Wonderful insights. Words in music bother me if I'm trying to write or think. Even if I don't know the language, I tend to look for words. But this doesn't seem to be a problem with Wim Mertens' music. He makes up a kind of language that's neither words nor vocalizing. The voice becomes an instrument.

But there's one composition that I seem to be most productive when listening to it, Steve Roach's Structures from Silence. It's a perfect synthesis of repetition and change. You feel the music but don't think about it. https://youtu.be/AsIjyJvhR9A
