I guess one of the very first associations for most people when mentioning rock music would be the electric guitar. That sweet electrifying sound of intense energy that goes from the tip of the fingers, through the pick and into the strings can surely get you going even if you’re not a fen. Originated as "rock and roll", rock music is a broad genre of popular music in the United States in the late 1940s and early 1950s, developing into a range of different styles in the mid-1960s and later. Like pop music, lyrics often stress romantic love but also address a wide variety of other themes that are frequently social or political. The list of great rock bands is quiet solid, but to name a few of the legends – The Beatles, The Rolling Stones, Led Zeppelin, Black Sabbath, Aerosmith, Guns’n’Roses, Queen.
