The late 70s/ early 80s was one of the great periods for popular music.

There really hasn't been anything like that explosion of musical creativity since- not that I've noticed, anyway.
Some of my favourite music from the period came out of the fusion of punk and reggae. Here's the New Age Steppers, with the incomparable Ari Up on vocals:The New Age Steppers - Fade Away
