Portal:Rock and Roll/Intro

Rock and roll (also spelled rock 'n' roll, especially in its first decade), is a genre of music that emerged as a defined musical style in the Southern United States in the 1950s, and quickly spread to the rest of the country, and the world (rhythm sample). It later evolved into the various sub-genres of what is now called simply 'rock'. As a result, "rock and roll" now has two distinct meanings: either traditional rock and roll in the 1950s style, or later rock and even pop music which may be very far from traditional rock and roll (rhythm sample). From the late 1950s to the late 1990s rock was perhaps the most popular form of music in the western world.
