Andy Gill from The Independent wrote: "It's a burly collection, with the band's flanged guitars and proggy synths asserting their refusal to follow any set style, and Hayden Thorpe's bristling vocals similarly stretching indie constraints; but when the only "new" track is jerry-rigged together from two old tracks, it all seems a bit unnecessary."[4] Steven Loftin from The Line of Best Fit praised the vocals from the album, by saying: "The vocals of Hayden Thorpe and Tom Fleming, entwining with their falsetto and baritone beauty respectively, have always been impeccable in a live setting, and it's great to hear this forever immortalised as they run through key cuts from their back catalogue here."[5] Phil Mongredien from The Observer stated: "It's unfortunate that [the album] draws rather so heavily on material from 2016's Boy King, the first Wild Beasts album on which memorable moments were in short supply. It all adds up to a slightly anticlimactic exit for a great band."[6]
