Blurryface is an apt title for a duo whose musical identity is tricky to make out. Tyler Joseph and Josh Dun have been scuffing the lines between rock, hip-hop and electro since 2011, and now they’ve added reggae, dubstep and folk-rock stomps to the mix. What gives the sonic zig-zagging focus is Joseph’s candour–whether he’s consumed by love (“Tear In My Heart”) or wrestling with which direction to take his songwriting (“Lane Boy”), listening to him unpick his troubles is consistently compelling.
