A collection of unreleased mixes by R.N.A. Organism, a unit representing the postpunk era in Japan that is gaining momentum for reevaluation. The unit's only LP, "R.N.A.O Meets P.O.P.O" (Vanity 0006, 1980), featured supercheap alternative-dub with various gadgets against a backdrop of urban aphorism and electrominimalism. Their sound has been described as "Japan's original mutant pop" mainly overseas, and their reissue of Vanity's work has been a hot topic.

In 2020, they released "Unaffected Mixes", a collection of unreleased mixes exclusively for the Vanity label box set, and the release of the mixes on Individual issuance was eagerly awaited, but it has been revisited in the form of "Unaffected Mixes ±", which contains slightly different tracks. At first listen, the impression of this album is quite different from that of "R.N.A.O Meets P.O.P.O". From the many fragments recorded in the studio at the time, the members/producers cut, pasted, and edited these recordings to show the direction of the unit more vividly. Nevertheless, both are valuable records provided by a recipe that resonates with the industrial sounds that emerged around the world in the late 70s and early 80s, and they are also proverbs from an inorganic life form that mutated into mixed noise in the midst of COVID.

"R.N.A. Organism's sound is an intricate combination of their own ironic humor, chilling minimalism, and schizophrenic sound collage." Tsutomu Noda (from the liner notes)
