I know ... Everything has been said, or nearly thirty this album, already mythical and legendary ... Yes, I know Bon Scott is absolutely irreplaceable and his voice IS AC / DC !! Yes I know that after him the band never more been quite the same ... Maybe, maybe ... "Back in black"? But ... VOICE was gone ... And every time I take my foot to turn this cake of kings on my plate I bow, in rhythm, before much genius! ... It's lyrical, square millimeter, virtuoso, inspired, punchy, exciting, exhilarating, in a word, pure and raw Happiness And as we say today: "It tears serious" But here, for real! ... Yes AC / DC is a credit to Rock, the real one, which today draws some dinosaurs that escaped the terrible and relatively recent glaciation music ... This eternal Rock, some songs will haunt your memories to death and you invade each and every riff, a poignant but vibrant nostalgia ... Well ... thank you
