"Hells Bells" sets a mournful tone with its slow, ominous build, but once Johnson leans into the mic, the band is back in business. From there on out, it's a masterful metal adventure that features some of the heaviest and most fist-pumping music of their career, including "Rock and Roll Ain't Noise Pollution" and the tune that's probably inspired more late-night sing-alongs than any other, "You Shook Me All Night Long."
