This Frank Turner and the Sleeping Souls – that most supple, dexterous and punishing of permanent backing bands – did, putting in hard hours as the nights drew in over a practice compound in the Oxfordshire countryside. As always, the trick lay in translating the album as it existed in Frank’s head to the point where others in his organisation were happy to lend their shoulder to its cause. The key to this exercise lay with producer Butch Walker. A noted singer-songwriter in his own right, as a technician Walker’s name appears on the production credits of albums by artists as diverse as Katy Perry, Hot Hot Heat, Pink and Fall Out Boy. But it was the American’s organic quality that caught the Englishman’s ear, his capacity to transport songs forged amid the thunder of the practice room floor to the exacting standards of the studio without compromise.
