One of four albums released in 2013, 「健忘症」 (Kenboushou) returns to digital services on Oct. 27, 2023, remixed and remastered.

The albums preceding 「健忘症」 mostly consisted of music written in the 1980s and 1990s, but 「健忘症」 had nothing but newly-written material at the time of its initial release.

But the excitement of showcasing new songs resulted in a rushed album with a subpar mix. So Eponymous 4 went back to the original tracks and gave them thorough renovation. While the source material stayed the same, the new mixes inject a sense of energy missing in the original release.

Pre-order for the digital download is available on Bandcamp.
