If you didn't see AC/DC by June, 2010, then I dare say you never *really* saw them, if anyone wants to be purist about it, as this was the last time the classic Brian Johnson lineup was together on stage. Having said that, I'm sure the upcoming tour will be quite good, especially if age is factored in. Time was that Angus would be so animated in his performances, charging across the stage like he was leading the band into battle, and fluffing very few notes or missing cues due to his frenetic movement, which will never not be hugely impressive. Unfortunately, he's just too old these days (68) to do that kind of thing anymore, save maybe a bit of a token duck walk and some moderate headbanging, but nothing like the constant motion he was in pretty much up until the Black Ice tour concluded. Due to what they've done up until now, I would say they're my favourite band of all time due to their music, their attitude and their work ethic. They've hit the mark on hard rock in ways that other bands who did the genre never quite managed, due to just not compromising. No wishy-washy mandolin stuff like Zep. No cock-rock like Coverdale and Leppard. Just hard, blokey ROCK with great hooks. I've heard a lot of bands cover AC/DC but very, very few really nail it because, yes, you can learn the songs, but that feel the originals are played with is so, so hard to cop, not to mention the guitar sound which is just wide-open and clear yet heavy as anything. Most guitarists will play the stuff with far too much gain which actually makes things sound so much smaller and weedier.
