I'll admit, even though I'm an 80's feller, I never really listened much to Rush. I have heard Subdivisions though, and this is an interesting track. I like the synths you used, everything matches pretty nicely. I think it would definitely sound better with some vocals. The originals vocals wouldn't really work since this is an electronic version, it would probably sound a bit off. But if one could find someone doing an acapella of this in the same tempo? Could be interesting.
Anyway, cool song man! Keep it up!
