Well yeah, that's the way I feel. First it hits you, and then you make the effort to figure out what's going on. I'm not prone to expending effort figuring out something that I don't want to hear over and over again...
I've at times been credited with being "eloquent" or some shit. No such thing. It's just that if something really gets to me, once I get over the intial buzz/repulsion/ehatever, I go about trying to figure out why I've had that reaction, and what specifically it is in the music that has produced that reaction. Now, yeah, I'm a musician, so I can go more "technically" into it than a lay listener (and that takes care of the "how), but still, I'd think that anybody could ask themselves "Why?" one way or the other, and come up with an answer, unless you just want to function entirely on gut reaction and keep moving on (which is certainly a lifestyle with immense appeal, but also one which I personally have found myself unable to sustain for any meaningful duration after numerous attemps. Personal wiring and such, I suppose...)
For me and Unit Structures the why was really pretty simple, and contained in the album's title - the structure. I was shaken (and stirred!) by all this intellegent energy feeling like it had an overriding structure (a structure which became apparent over time, as I pursued the "how"). The notion that "structure" and "freedom" could exist on such equally large a scale had a very powerful primal impact & appeal to me, then and now.
And besides, "Enter Evening" is just flat out beautiful, at least to me.
