"Notwithstanding the way of formulating the music, those keeping an eye on the idiosyncratic Finns' oeuvre since their 2010 debut won't be too surprised by their literally titled fourth album: the familiar glam-rock stomp is present, as is the techno-inclined Acid House pulse. This time, though, there is a fluidity which must stem from the means of composition and how the resultant audio has been fused with bass guitar, drums, guitar and a raft of (mostly) analogue synths. Rather than a venture into new pastures, the energised IV is a recalibration".
