The Venezuelan musician published the single in advance on February 19th through her YouTube channel and announced it this way:

@@@@@ is a transmission broadcasted into this world from a speculative fictional universe, in which the fundamentally analogue format of FM pirate radio remains one of few means to escape authoritarian surveillance powered by a hostage sentience gestated by a post-singularity AI. The host of the show, known as DIVA EXPERIMENTAL, lives across multiple bodies in space in virtue of her persecution - in order to kill her, one would first have to find all of her bodies. The bodies that host her carry fetishes for paralinguistic, breaking the fourth wall and nurturing a mutant faith in love in the face of fear.

The text notes that Arca also considers @@@@@ as "kindred" to her 2013 mixtape &&&&&.
The new music is Arca’s first since their self-titled album from 2017, which was preceded by 2016 project Entrañas, which featured Mica Levi, and her 2015 album Mutant.

Today Arca affirmed that @@@@@ is "constituted by discrete musical quantums", and that "each quantum has a title":

Furthermore Arca will be on tour from spring 2020. Here are all the venues:
