ACD are unique, many have tried to copy them and many such as Krokus and Airbourne actual do sound like them but there is only one ACDC. They are special, Angus and Malcolm just have something that no-one else does. I saw them at Subiaco Stadium in Perth in 2010 and I am so glad I made that trip. This is a band that you can truly hear 8km away. The albums with Bon Scott will always be my favourites but there is no such thing as a kak ACDC album.
