In February 1980, AC/DC frontman and lead singer Bon Scott died suddenly (but not unexpectedly given his penchant for mixing booze and drugs in all-night parties). For most bands, the loss of a lead singer of Scott’s caliber would necessitate a major shift in direction to avoid a slow burn to irrelevance. But brothers Angus and Malcolm Young and the rest of the band quickly replaced Scott with Brian Johnson, who filled the shoes perfectly with a dead-on mimic of Scott’s scream and growl vocals. By July 25, 1980, AC/DC was back with their best album, Back In Black, and almost no one missed ol’ Bon when Brian was at the mic. With its predecessor, 1979’s Highway to Hell and follower, 1981’s For Those About To Rock We Salute You, Back In Black provided the world with a one-two-three punch of raucous, blaring rock that made AC/DC the biggest hard rock band in the early 1980’s. With nearly 50 million in unit sales, Back In Black is the #1 selling album by a group and the second highest selling album of all time behind Michael Jackson’s Thriller. It is available as a CD or individual mp3 files on Amazon, but not yet on iTunes. AC/DC is featured in Dr. Rock’s Playlist Vault.
