I like the ominous drone at the beginning and the smooth bass that comes in at :14. The progression is a little slow-paced, but the fun rhythmic elements of the synths at around :30 and build-up into :51 were very well-done. The growly bass section thereafter was a little drawn-out, but the build-up into 1:31 was catchy and enjoyable. The drop itself was pretty minimal, but I’m enjoying the rhythmic content and sound design. I’m enjoying the moody pads that fade in at 2:43 - it provides a nice element of contrast in the tone of the piece. Stripping away the drums at 3:25 was also a good idea, and the arpeggios at 3:37 served as a strong segue into the more energetic section at 3:50. I also appreciate how the second drop was different compared to the first. The more well-balanced and full-textured part at 5:07 was a good way of finishing the piece. Overall, I really admire the strong production quality and instrumentation of this one. My main complaint is that the texture is often very minimal and drawn-out, without a full use of the frequency spectrum a lot of the time. I would’ve liked to see some more melodic content at some point, or at least some more variation in the harmonies later on. The arrangement and some of the build-ups also sound pretty generic. Still, I’m really impressed with the rhythmic content and mastering. You’re a talented producer, LSI! Keep it up. :)

You definitely made me question how I perceive music in the first place (in a good way!).

However, there's some aspect of sound design that I think would require more attention:
I think that the volume of the reverb on the main melodic synth is too loud, or that some notes last too long, because at 0:33, 0:46, 5:15, 5:28, 5:40 and 5:54 the reverb tail or the notes accumulate too much. Furthermore, I was expecting some kind of variation at the end of the song, but the melody of this synth doesn't really progress ever. Also, I found the drops to be quite quiet. This kind of chorus has its own charm, but on another hand I enjoyed it less because of that (although that might be only me).

That said, I found the transitions to be actually geniune. Like, hell, from 0:51 to 1:16 was amazing. I had this feeling when, in some offline RPG, they suddenly throw you out of the routine they established from the beginning by letting you know that you're in the matrix or some other kind of surprising journey.

In my opinion, the sound design of the transitions was like 5x better than the sound design of the tail-overriding parts, and I wonder what caused such a discrepancy in (what I perceive as) quality.

Overall, pure dubstep is by far not my preferred genre, however I found this work very interesting and inspiring. Keep it up! <3
