We hit the sack, it’s been too long, we’re glad to be back. So what does one need for that authentic AC/DC sound? Marshalls, Gibsons, and the Young brothers. We got two out of three, which ain’t too shabby. It’s already been 40 years since this landmark album arrived, so it seems as good of time as any to dive into the classic title track. New singer? No problem. New sound? Nah, get outta here with that nonsense mate!
