The Beatles
How can you describe the impact of The Beatles on popular culture of the XXth century without using every superlative in the book ? The Four Fabs from Liverpool changed the way the music business worked, the way people approach listening to music, writing it and composing it, and each of their singles and albums remains an amazing testimony of the moment when Pop music touched perfection itself. And all that wrapped up in only ten years, until their 1970 separation.
