Post punk sounds and industrial towns go hand in hand. Detroit’s Protomartyr have a sense of urgency and anger that could’ve sprouted from somewhere like Manchester or Cleveland in 1979 but frontman Joe Casey’s lyrics could’ve only sprung from one time and place. With a half-sung, half-shouted delivery, Casey is a true original, spewing literate bile that is usually funny, bleak and thoughtful all at the same time, while his three talented bandmates match his words with dark, powerful, exceptionally well-crafted music. [...] Under Color of Official Right, has them firing on all cylinders with Casey pointing his lens at, among other things, coastal invaders of his Detroit, absentee dads, local politics and inter-band dynamics. Best new band of this decade.
