Weeping Choir was engineered by Kurt Ballou of Converge, who previously produced Full of Hell's 2017 studio album Trumpeting Ecstasy.

This time, guitarist and primary songwriter Spencer Hazard wrote full songs in his bedroom on his own and the band would get together to practice the new material about once or twice a month because of their new "adult" responsibilities.

Full of Hell reported that Ballou pushed the band harder this time than before, but ultimately best captured the sound of their live performances out of all their albums to date.

[7] The band also attributes their new ability to work in a studio and build a song around an electronic beat (giving "Angels Gather Here" as one example) to their experimental collaborative albums with The Body.

Vocalist Dylan Walker says they re-incorporated noise and electronics into Weeping Choir knowing they were absent on their previous album, and because they "wanted to make a well-rounded record again".

Hayter said it "was a great pleasure to work on" the song, and that she, "wanted my vocals to provide a counterpoint to all the savagery, to pick up on and accentuate harmonic things happening in the music in an unexpected way.

"[8] Full of Hell began promoting Weeping Choir with an online stream and music video directed by Cody Stauder for the opening track "Burning Myrrh" in March 2019.

[9] Full of Hell also released a Justin Broadrick (Godflesh, Jesu) remix of the track "Thundering Hammers" through Decibel magazine's Flexi Series in their May 2019 issue.
