According to Xiu Xiu, “Arp Omni” is “A little sweetie ballad about falling for a person who takes risks in life,” while “Veneficium” is about “Being lost; literally lost, emotionally lost, lost in a smashed psychological dimension beyond your control, being overwhelmed by the weight of one’s insignificance in the face of time, space and death, and pointlessly railing against what does not notice let alone care about you.”

The release of the two songs is accompanied by visuals, including a visualiser for “Arp Omni directed by Lin You, and an allegorical video for “Veneficium” directed by Luke Orlando.

Jamie Stewart shares: "A Veneficium is an instance of being poisoned or the preparation of magic potions or the substances that make up a poison. The point of any involvement with said substances or pursuits is at best meddling with risky and significant transformation and at worst taunting the nefarious, even up to the point of death. Either way, what lies in wait on the path to these in between and far away places from our present world is dangerous and unsettling and unknown. But perhaps also and why not, it could be being turned into a psychedelic BDSM train or the inspiration to benevolent and anonymous used toast and toaster delivery."
