Let's hear it for straight up no bullsh!t rock and roll.
On this album, AC/DC has captured and perfectly transmitted the idea of MASCULINITY. It's a man's record full of men's images and urges. Rock 'n' roll is basically a man howling about his desires, and he often desires women, liquor, and guitars that sound like sheets of metal being destroyed by power tools. It's a very simple thing, really.
