Opening with one of the most well-known guitar riffs in rock music, Heart’s Little Queen starts with a growl — a burning guitar tone that sounds like it originated from deep in the belly of a colossal and untamed animal. “Barracuda” harbors the undeniable sound of rage: not the strain of anger that renders you powerless and stewing, but the kind that burns so strong that it cuts you loose, lets you run free and leaves you no choice but to win. The sound is so indisputable because it embodies Heart’s origin story: one of wrath and the triumph that follows.
