The album served as the shot heard 'round the world, alerting all other musicians that the game had changed.

"There were so many components that were revolutionary, from the cover — there had never been a cover like that — to the storybook lyrics," says Lee Abrams, the 55-year-old senior vice president and chief programming officer for XM Satellite Radio. "The lyrics weren't about cars or girls or surfing. It was very cinematic. You could listen to it and it was almost like an audio movie.

"I think all of those groups, like Jethro Tull and Pink Floyd, really saw that album as a real kick in the butt. After 'Sgt. Pepper,' you find everyone from the Who to the Stones to Zeppelin opening up and using different instruments on their albums."

As the memories come flooding back, I have to say, the music was so much better in the late 60's and early '70's than it is today.
