Query: Music for the gym?

With its minimalistic, repetitive chords and rhythms, the music in these pieces contains little in the way of traditional "development." This music progresses by flowing along rather than by forming an elaborate structure. As I listen, I feel as if I'm on a treadmill, sometimes walking faster, sometimes slower, but not really getting anywhere. My mind wanders, and I find myself thinking about other things rather than about the music. Perhaps this is how Glass wanted it to be. He has written a lot of film music, and much of his music does, indeed, seem like accompaniment.This is not unpleasant music. But I find it something less than totally rewarding--seems more like the composition of a amateur.
