I realise this is a bit deconstructed of me.
But this is flawless metal, it features Bon Scott before he choked to death on his own vomit, and Angus Young is clearly as mad as a box of frogs, to the extent he manages to break his Gibson. Just great rock and roll. Lots of very loud noise, people being stupid. I think my friend Saffire would approve of the principle.
Insane, relentless audio attack, and I absolutely adore it, even at my advanced age. If you disagree, fine. Shove it.
