Brilliant, mate.
AC/DC stood the test of time. There is never anything that can go wrong with good, loud, 3 chord hard rock songs as epitomized and perfected by the Young brothers, et al.
I first became aware of AC/DC in 1979, when Highway to Hell came out. American rock was pretty much sucking then (Styx, Cheap Trick, Kiss), and I had gotten tired of British punk rock. AC/DC was like a shot out of the blue that reminded every one just how killer simple, loud guitars and drums sounded when capably performed.
I heard Angus Young once say that AC/DC could only have come from Australia, because American record companies of the late 70s were not down with the that raw sound they had....they were looking for singers like Styx and Journey. Bon Scott did not fit the bill!
Anyway, thank you AC/DC for rescuing rock from a death spiral epitomized by REO Speedwagon and other crap bands! I was "Thunderstruck" by you dudes!
