After announcing the Christmas Day single a few days prior, Kelsey Lu and Yves Tumor unveiled their debut collaboration "let all the poisons that lurk in the mud seep out" that features Kelly Moran and Moses Boyd.

Lu said of the atmospheric outing, ""let all the poisons that lurk in the mud seep out" is about taking risks and diving headlessly into the unknown while being wholly yourself. Deconstructing the poisons that brought you doubt and mania as to the powers that lies within and accepting that whatever is evil will come to light while bending oneself backwards to embrace their true nature and the depth that lies within."

The new song is Lu's first release since May's "Morning Dew", and is Yves Tumor's first outing since appearing on Joji's Nectar track "Reanimator" in September.

It also marks Moran's first collaboration since releasing her Chain Reaction At Dusk split album with Prurient earlier this month, and is Boyd's first feature since appearing on Village Of The Sun's "Ted" track in April.
