Liking any kind of heavy metal was seriously uncool when I was a teenager. It was considered music for the 70s generation of teenagers, who came just before us.
There was a few fellas in my class at school who wore denim jackets with AC/DC and Black Sabbath iron on patches.
It was considered rude to laugh out loud at them. Like laughing at disabled kids.
I only discovered AC/DC about 5 years ago. It is OK to like them now I am older. Coolness does not exist for people in their 40s.
Anyway the early stuff is great. The mid 80s stuff not so much. I thought Black Ice was one of their best so I was looking forward to Rock or Bust.
Verdict: meh/OK
Not as good as Black Ice but pretty solid and not their worst.
