Logical
I'm so sorry...this following review was accidentally posted to Surface; I intended it for this piece (Infernoplex).
Your technical mastery of this style is improving very nicely. You have a unified piece with two main motifs---and you stuck with both of them. Almost every note followed logically from the previous---something that a lot of pieces on Newgrounds lack. It is this prevailing logic that gives your music so much mass. Every note has more mass if it isn't just carelessly put there to fill the gap between point A and point B.
The electric guitar soli are very unique; their melodic lines are mature and it doesn't have "too many notes" just to fill in the harmony, a problem that some of your earlier works ran into. Again, I like the musical logic in the construction of these solo lines.
The first motif is introduced immediately at the start of the piece, and heard throughout the piece. As for the second one, you teased it out of the music little by little---a very thoughtful way of exposition. First it appears in a fragment in the fast runs at 0:17-0:19, then at 0:50-0:52, then at 2:00-2:02. You finally expose the whole thing at 2:06 in the guitar line...but you only show us the melodic outline. You're still not done teasing us. The real thing finally starts at 2:17. Then you developed the guitar line further by manipulating the harmony(!) starting at 2:44. The first motive returns once more for a little while and the piece ends.
Harmony---you used more than 4 different harmonies! Your earlier works had completely predictable harmonies. Not any more in this piece! I'm so happy now. This variety is so rare in electronica that I will simply leave it at that.
Regarding the rhythms used.... The first motif has a clean and distinct articulation (I mean the thoughtful act of separating a note from the next by a tiny gap), and provides a nice background to the rest of the piece. Your second motif blew me away. Its ascending melodic line and regular, angular attack really provided the "oomph," and as a result we reallllly want to tap a collection of our body parts when it came up.
By the way, your second motif is one of the most thoughtful and unique one I have ever heard in this entire genre to date. I think it's because it "climbs up" in a regular, well-cut rhythm, giving it the restless feel. When I say "genre," I mean electronica of any kind. You have taught us that speed is not the same as momentum---it also involves the mass of the music. (Physics pun intended.)
Architecture: I like the rounded-binary construct. You had a section 1, a section 2, and a little return to section 1 at the end. This satisfies the listener's need for unity and symmetry. At least that's what the textbooks say....
This is your best work (counting Surface).
