I actually found partial samples of three other songs by doing a web search. Decent samples, too, approx an intro, verse, and chorus of each. I like them even better than the "single" so far.

Haven't listened to enough of the stuff to have an opinion formed yet. And of course, I need to hear the whole album in full not-compressed-to-within-an-inch-of-its-life form. But my impression so far is that they're continuing the progression they started with the directions that Counterparts and Test for Echo were taking, i.e., this one is even harder and edgier. In fact, this one kinda reminds me of Tool so far. Which is interesting, because I figured that Tool was influenced by Rush, not the other way around.
