Two machines?
I was thinking this would be a really incomprehensible work until you said exactly what it was. It still manages to be pretty effective by giving the listener exactly what the title says. It does get monotonous after awhile, but that is to be expected in something so short working on an infinite loop. This probably would be suitable for something like a technological submission. It seems at one point that they seem to be working together as in hitting each other. The latter half made it seem like they were going side by side in something.
