Claude says:Biffy Clyro's 2007 turn toward melodic alt-rock on Puzzle caught you in early 2011, a Scottish band shedding some of their heavier edges while keeping the emotional weight intact. You cycled through the whole thing a handful of times over the next couple years, gravitating toward tracks like "Living Is a Problem Because Everything Dies" and "Saturday Superhouse"—songs that balanced intricate arrangements with genuine heaviness.
