The band's lead songwriter, J Willgoose, Esq., described the album's premise as an allegory for today's "abandoned and neglected communities across the western world", which have led to a "malignant, cynical and calculating brand of politics."

The band made use of a community hall formerly used as a convention space by the town's local workers' institute for the album's recording.

It also features guest appearances by Welsh musicians James Dean Bradfield and Lisa Jên Brown, Scottish singer Tracyanne Campbell (of Camera Obscura) and English band Haiku Salut, as well as the Beaufort Male Choir.

"[2] "Progress", the fourth track on Every Valley, was inspired by the sound of Kraftwerk, with its bass line and use of a vocoder drawing parallels to the tropes of the German electronic group.

He also affirmed that "Progress" is "an attempt to state that more explicitly, especially at a time when certain regressive elements seem determined to take us back to some non-existent, halcyon 1950s era.

"[4] The band traveled to Ebbw Vale, Wales, a former steelworks town to record Every Valley in the lecture hall of a defunct workers' institute.

[3] Four featured artists appear on Every Valley, including two of Willgoose's musical heroes – James Dean Bradfield, the frontman of Welsh alternative rock band Manic Street Preachers, and Tracyanne Campbell, the lead singer and guitarist for Scottish indie pop band Camera Obscura.
