Never change, AC/DC. Do you ever just stop and think about AC/DC? I do. They fascinate me as a band because they simply figured out what they wanted to sound like early on and then just, like, stuck with it. Over the years, they've actively refused to evolve their sound, with Angus Young even openly mocking the idea that they'd want to, and yet they still made a huge mark on the world of rock, because the sound they were so stubbornly committed to was really, really good.
