"'IV' is a thrilling diversion from the more straight-up rock of 2017 predecessor 'Night People'. The band now merges genres confidently and coolly, creating carefree indie pop tracks, yet always reserving a seat for their rock band roots. As balancing acts go, they've played a blinder - it's a pleasure to see them testing the limits of their sonic template, and impressive that they're continuing to do so on their sixth album".
