ROCK & ROLL

Rock and roll, rock'n'roll, rock'n'roll is a genre of rhythm, derived from a mix of different genres of American folk music (rhythm and blues, hillbilly, blues, country and western are the most prominent) and popularized since the 1950s, and its most influential singer Elvis Presley, most influential guitarist Chuck Berry and most influential bands The Beatles and The Rolling Stones.
The term "rock" is derived from the rock and roll "a distinctive and popular musical genre in the 50" and each of the various musical genres from rock and roll. However, whether in practice there are many artists in rock music, rock and roll without making the 50, continue to call their music "rock and roll."
