What Highway to Hell has that Back in Black doesn't is Bon Scott, AC / DC's original lead singer who died just months after this album was released. Scott had a rusty, raspy, scream of a voice, like he might break into a coughing fit at any moment. In other words, on crunchy, hook-heavy metal classics like the title track and on "Get It Hot" which is more roadhouse rock than metal, he had the perfect instrument for such wild-living anthems. Too perfect, it turned out. --David Cantwell
