Ultra 85

The album was initially announced by Logic on May 5, 2017, through a hidden message, which was contained within a booklet included with physical editions of his 2017 album Everybody. The album is intended to be released alongside Logic's science fiction novel of the same name, with the latter released on September 17, 2024.

On January 17, 2025, Logic released an extended play of leftovers during the Ultra 85 production, titled Aquarius III.

The album received critical acclaim. Reviewing the album for AllMusic, Neil Z. Yeung described it as, "Vibrant, exciting, and back to basics, [the album] is a blessing to fans willing to dig into the lore, and could even be an accessible entry point for casual listeners digging into his entertaining wordplay, underrated flow, and old-school production." and called it a "multimedia experience that doubles as one of the stronger, more mature efforts in his catalog."
