Seriously eyeing to blues, "Stiff Upper Lip" fully reflects the taste of renewed AC / DC for the blues, a style that has always influenced, without always having been put forward. Not as good as Ballbreaker, he climbs still a very qualitative level, like the title track as an opening, which devastates everything in its path. I do not consider this record as essential if one wishes to be highly selective in a choice on the band's discography. by cons, this album remains a must for any fan who respects !!! production is exemplary, the technical level too, about the inspiration, it is to wonder how they manage to lay hits to tail single file ...
