Any serious rock fan has to only mention AC/DC’s name in any conversation to get sage old head nodding in approval and younger fans salivating as they prepare to hear more tales of one of the hardest rock acts to grace the genre in 40 years. From their 1975 debut High Voltage (Australia, 1976 elsewhere) through to the superb Dirty Deeds Done Dirt Cheap, the career defining Back In Black and finally the 1988 Blow Up Your Video, fans knew what to expect and they devoured each album in their droves.
