I picked not only one of the greatest rock bands of all time but one that sound has never been duplicated mainly because I think Angus and Malcolm Young wrote very distinctive guitar riffs. If you do your research you can simply find that in the late 1970s and early 1980s a lot of other bands were "trying to sound" like AC / DC, the Swiss band Krokus, for instance, comes immediately to mind. Yet, despite the many posers, you could always tell when it was and when it wasn't the real AC / DC. I mean every time you hear "thunderstuck" on the radio you know what song it is in under 2 seconds. Am I right?
