The Beatles

In the ' 60s four boys of Liverpool redefined forever the concept of pop music (originally were five) and from then nothing was the same, fans followed them outside where they were as if they were legions, the concerts which were full immediate.

Ringo Starr, John Lennon, Paul McCartney and George Harrison recorded 13 albums of study until its dissolution in 1970 (many people said that it was because of Yoko Ono:-p). They have all kinds of songs the Group had a very important evolution during those 13 albums.
