Joe Casey (vocals), Alex Leonard (drums), Greg Ahee (guitar) and Scott Davidson (bass) have been making top-quality post-punk as Protomartyr (above, performing “The Devil in His Youth” for Pitchfork) since forming the band seven years ago in Detroit, trafficking in energetic yet melancholic songs—with frontman Casey earning comparisons to Nick Cave and Ian Curtis along the way. The quartet’s fourth long-player, Relatives in Descent (stream it below), came out about a month ago to raves: “Alex Leonard pounds the skins and shifts through impressively complex percussive work, while Scott Davidson provides chugging grounded bass below Greg Ahee’s dissonant and virtuosic post-punk wailings. It’s Joe Casey’s driven melismatic, charismatic and poetic crooning however that adorns and brings each fragmented arrangement to life,” gushes the Line of Best Fit. “It really is about time we all sat up and started to take Protomartyr seriously. Their quality of music and precision is outstanding.” And not to be outdone, the Guardian calls it “sensational, bloodied but unbowed post-punk.” Find out how it all comes together live (spoiler alert: pretty great) when they close our their American tour at Music Hall of Williamsburg on Saturday night. D.C. trio Flasher and Brooklyn quartet Weeping Icon open the show.
