I've loved this song since I first heard it in the early 1980s. It's amazing to think it's been that long: when I first saw the film, its central message seemed to encapsulate a world fraying at the edges. In retrospect, it was actually a golden time compared to the shitshow we're currently living through. Anyway, "The Grid" is the obvious highlight of the record, and its shifting sense of psychedelia has stayed with me ever since.
Seeing the notation for the song, though, was the moment in which the real importance of the music hit me. It's an unerringly accurate representation of what it feels like inside my mind. Everything is ostinato, and the patterns constantly shift, repeating, jumping, and underlining the power and intensity of the voices within. More than that, the intervals which pulse through those patterns give the impression that the song is moving from half-time to double-time. In reality, of course, the music merely keeps its steady state, moving relentlessly forward. There's a deep sense of wonder to see the shifting components of the song move and fragment - then coalesce once again. It's a dance, and it's the heartbeat of my life.
