Why is 60's music the best ever in rock history?

What happened on the run up to and during the 60's that spurred on a revolution in rock and roll that lives on today as arguably the best and most creative decade in rock history?

I'm going to look at some of these and drop in some amazing music links too. And if you don't already think so, you'll soon agree that there has never been such an incredible decade. So watch this space.

Probably the first thing to happen that influenced the music of the 60's was the blues.
