Four chords can change the world.

Margaret Mead said "Never doubt that a small group of committed citizens can change the world, indeed it is the only thing that ever has." Musicians would disagree. About once per decade, when the music scene is getting stale, something new comes along BOOM blows the barn doors open. These are pivotal moments when the course of rock and roll, indeed, "the world" is forever changed. Often the song itself is very simple; four chords, very sparse lyrics, but infectious, unforgettable, and unlike everything around it. Over the next few days I'd like to post what I think have been the most influential moments in rock and roll for each decade. Feel free to disagree, or comment, or flame. But don't get yourself too worked up "I know it's only rock and roll...but I like it."
