I wasn't gonna review the sections before but seeing how many amazing tracks didn't make it into CE i might as well.
The 2 unique tracks to this release are both standout in sound and style compared to most of the other ikd-sj discography, Perpetuel being a quiet piano ballad very similar to "World's end" but more clean and using a lot of other samples and sounds along with featuring multiple vocals at the same time wich even if it doesn't hold the same impact its still a really cool and interesting track. And as for Chapter Kiku it inmediatly reminds me of a Fragile era NIN song, especially that weird guitar in the background and also Akira's vocals do sometime do that same weird voice as Reznor so another really cool song i like.
The other 2 tracks are both like musical perfection but i might as well review them when i listen to CE.
